ACS Catalysis 'Under Review': What Each Status Means and When to Expect a Decision

ACS Catalysis operates the Editor + Associate Editor model. ACS Catalysis Associate Editors are working researchers in catalysis, not professional editors; the senior handling Associate Editor reads the entire paper and evaluates catalysis-significance, mechanistic interpretation, benchmarking adequacy, and ACS Catalysis subspecialty routing across homogeneous catalysis, heterogeneous catalysis, biocatalysis, photocatalysis, and electrocatalysis.

An Associate Editor at ACS Catalysis typically handles 60 to 120 manuscripts per year and spends 30 to 90 minutes on the initial read; ACS Catalysis Associate Editors are active researchers fitting ACS Catalysis editorial work around their own laboratories.

ACS Catalysis editorial culture is decisive: editor triage focuses on whether the paper demonstrates genuine catalysis significance, and triage decisions are made expediently. Papers that pass the ACS Catalysis Editor + Associate Editor screen have cleared the steepest filter in catalysis specialty publishing.

Before the paper reaches external reviewers, an ACS Catalysis Editor or Associate Editor evaluates whether the catalysis-significance warrants ACS Catalysis's selective editorial slots. Manuscripts sufficiently lacking in novelty or new insights may be rejected without external peer review, with these decisions made expediently. About 40 to 50 percent of submissions are rejected at this stage.

A desk rejection most often means the editors concluded that benchmark comparisons are weak (roughly 35 percent of desk rejections involve benchmark tables using outdated or selectively chosen comparisons that overstate the advance relative to the actual field standard), mechanistic interpretation lacks direct spectroscopic support (roughly 25 percent of desk rejections involve mechanistic interpretation resting on computational prediction or plausible inference without direct spectroscopic support), or the work would fit better at a sister ACS journal (JACS for broader chemistry, ACS Sustainable Chemistry & Engineering for sustainability cascade, ACS Energy Letters for energy catalysis).

The ACS Catalysis editorial office confirms files are complete: manuscript with figures embedded, Supporting Information with characterization data (NMR, XRD, XPS, BET surface area where applicable, catalytic activity tables with turnover frequencies and selectivities), benchmark table comparing to current field standard, cover letter directed to the Editor, conflict-of-interest declarations, ethics-statement documentation, and data-availability statement.

The Editor or Associate Editor reads the paper and evaluates catalysis-significance, mechanistic interpretation adequacy, benchmark comparison against the actual field standard, and ACS Catalysis subspecialty routing.

In parallel with the primary editor's read, ambiguous-fit papers are discussed across the ACS Catalysis editorial team where peer Associate Editors weigh in on whether the paper would fit better at ACS Catalysis or at sister ACS journals. This editorial-team discussion runs alongside the desk-screen and adds 2 to 5 days to the timeline that is invisible to the author in the portal.

ACS Catalysis Associate Editors typically invite 2 to 3 external reviewers, with reviewer recruitment typically taking 7 to 14 days. The recruitment window can take longer because reviewers with topic-matched catalysis subspecialty expertise (especially across the homogeneous-heterogeneous boundary or the biocatalysis-photocatalysis-electrocatalysis boundaries) are scarce.

Once reviewers agree to review, the typical ACS Catalysis peer-review cycle lasts 2 to 4 weeks per reviewer. One community-reported first review round example is 3.7 weeks. Reviewers are asked to evaluate catalysis-significance, mechanistic interpretation rigor, benchmark adequacy, and reproducibility. Reviewer reports for ACS Catalysis tend to be focused; 1500 to 3000 word reports are typical.

After reports return, the Associate Editor synthesizes them. Total submission-to-acceptance commonly runs 3 to 6 months for successful papers, including revision rounds.

• Rejection within 1 to 3 days: Administrative issue or immediate scope mismatch.

• Rejection within 3 to 10 days: Editor + Associate Editor desk rejection per the expedient triage policy.

• Still Under Review after 2 weeks: Strong signal. Paper passed the ACS Catalysis editor filter.

• Still Under Review after 8 weeks: Reviewer-recruitment or reviewer-report delay. A polite inquiry via the ACS Paragon Plus portal is appropriate.

• Status changes to "Decision Pending": Reports are in; expect a decision within 1 week.

This is the most common anxiety we hear from ACS Catalysis authors during the active editorial window. The honest answer: no, 4 weeks at Under Review puts you right at ACS Catalysis's ~3.7 week first review round example. Reports may already be in editorial synthesis with the Associate Editor preparing the recommendation. Most reviewer-driven delays come from reviewer-recruitment timing for catalysis subspecialty experts rather than slow reviews.

If the portal still says Under Review at the 7-week mark, the most likely explanation is that one of the assigned reviewers asked for an extension and the Associate Editor granted it. This is normal practice at ACS Catalysis.

What you should NOT do during the 4-to-7-week window is email the editorial office. ACS Catalysis Associate Editors are working researchers managing 60+ active papers per year around their own laboratories; an inquiry at 4 weeks adds friction without accelerating the timeline.

If your ACS Catalysis paper is rejected after review, the natural cascade depends on what the reviewers and Associate Editor cited:

JACS is the natural ACS broader-chemistry cascade for catalysis papers where the catalysis priority bar of ACS Catalysis is not met but the broader chemistry significance is high. JACS uses ACS Paragon Plus at ACS journal page; editorial contact jacs@acs.org.

ACS Sustainable Chemistry & Engineering is the ACS cascade for sustainability-focused catalysis papers.

ACS Energy Letters / ACS Applied Energy Materials are ACS cascades for energy catalysis papers.

ACS Catalysis Au is the ACS open-access cascade for catalysis papers where open-access fits.

Angewandte Chemie is the external Wiley cascade for top-tier catalysis Communications. Angewandte Chemie uses ScholarOne at ScholarOne submission portal; editorial contact angewandte@wiley.com.

Nature Catalysis is the external Springer Nature top-tier catalysis cascade. The Nature Catalysis Manuscript Tracking System at mts-natcat.nature.com handles submission; natcatal@nature.com handles publisher-level inquiries.

ACS asks reviewers at ACS Catalysis to evaluate four things specifically. The table below maps each to actionable preparation.

Across ACS Catalysis manuscripts, we see three patterns generate the most consistent reviewer concerns and the most common reasons papers miss the editorial bar or fail the desk screen. These are not claims about hidden ACS decision data; they are recurring Manusights observations from catalysis, chemistry, and materials manuscripts prepared for ACS-family venues, cross-checked against public ACS Catalysis author guidance and the journal's visible emphasis on novelty, insight, and reviewer-ready evidence.

Benchmark-table inflation is the fastest way to lose editorial trust. In ACS Catalysis-targeted drafts, the benchmark table is often present but not honest enough for the paper's central claim. The common weakness is selective comparison: old catalysts, favorable temperatures, different substrate scope, different solvent systems, or missing selectivity and stability columns.

Reviewers do not need to reject the catalytic activity itself to reject the manuscript; they can reject the claim that the activity is an ACS Catalysis-level advance. The strongest submissions normalize conditions, explain unavoidable non-equivalence, include unfavorable comparators, and make the actual advance visible without forcing the Associate Editor to rebuild the field standard from the reference list.

Mechanism claims fail when the evidence stack is thinner than the language. Many ACS Catalysis manuscripts write a mechanism section as if plausible DFT, product distribution, or post-reaction characterization proves the catalytic pathway. That mismatch is where reviewers become severe.

If the manuscript claims active-site identity, intermediate formation, rate-determining steps, or catalyst reconstruction, the evidence should be matched with kinetic data, isotope experiments, operando or in situ spectroscopy, poisoning/leaching controls, surface characterization, or a clear statement that the mechanism is proposed rather than established. A narrower but well-supported mechanism claim is usually safer than a broad mechanism narrative held together by inference.

ACS-family routing is a scientific argument, not only a prestige choice. We frequently see rigorous manuscripts aimed at ACS Catalysis even though the central contribution is broader molecular chemistry, energy-device behavior, environmental application, or sustainability process design. That can make the ACS Catalysis abstract feel unfocused: the manuscript asks the journal to value everything equally. Stronger papers name the catalysis insight first, then explain why the application matters.

If the catalysis insight is secondary, the better route may be JACS, ACS Energy Letters, ACS Sustainable Chemistry & Engineering, ACS Applied Materials & Interfaces, or a specialist catalysis journal. Preparing that fallback before the decision arrives makes a reject-after-review much less costly.

Source limitation: Manusights cannot see private ACS reviewer activity, queue state, or editor notes. This page combines official ACS guidance, public status/timeline signals, and Manusights manuscript-review patterns; use the ACS Paragon Plus record as the authority for your individual submission.

This page was created from ACS's public ACS Catalysis author guidelines at ACS author guidance, ACS Paragon Plus documentation (Editor + Associate Editor expedient triage, ~3.7 week first review round example from community reports, benchmark-table desk-rejection criterion at ~35 percent, computational-only mechanism desk-rejection criterion at ~25 percent), SciRev community-reported transit data on ACS Catalysis, and Manusights pre-submission review experience with ACS Catalysis-targeted manuscripts.

For the ACS catalysis landscape beyond ACS Catalysis, start with the ACS Catalysis submission guide, ACS Catalysis review time guide, ACS Catalysis cover letter guide, and ACS Catalysis pre-submission checklist. For routing comparisons, see JACS under review and Angewandte Chemie under review.

The choice across these titles depends on whether the central contribution is top-tier catalysis priority, broader ACS chemistry, sustainability-focused catalysis, energy catalysis, open-access ACS catalysis, or top-tier chemistry Communications.

Reviewers at ACS Catalysis typically draw from 2 to 3 catalysis subspecialty experts. Editors screen and triage manuscripts before any external reviewer sees them, and preparing a response template that addresses both mechanistic-rigor and benchmark-adequacy perspectives accelerates revision rounds substantially.
