A recently published essay lamented a perceived negative impact on chemistry associated with diversification of the work force. The contribution also made disparaging comments about research carried out in specific countries. That contribution, coupled with the great evidence of broader societal discrimination and prejudice against minorities of all types, in many different contexts, compelled the unusual step of ACS Catalysis crafting a statement from our editorial team.

The Burden of Disproof

Susannah L. Scott. "The Burden of Disproof", ACS Catal., 2019, 9, 4706-4708.

A feature that distinguishes ACS Catalysis from other journals containing the word “catalysis” in their titles is our intentional focus on fundamental or conceptual insight into catalytic phenomena. This criterion is stated in our instructions to both authors and reviewers. In many of the papers that we publish, insight emerges from investigations into how a catalytic reaction proceeds at a molecular level, in other words, the reaction mechanism. Why is this information so important to ACS Catalysis and to catalysis science in general? The most powerful advances in our field are often those that improve our ability to make predictions about catalyst performance (activity, selectivity, productivity). In general, as our fundamental understanding of a chemical reaction becomes more complete, the range of accurate predictions becomes broader. This Editorial discusses the question of what constitutes evidence for a catalytic mechanism, as well as how mechanisms should be evaluated.

A Matter of Life(time) and Death

Susannah L. Scott. "A Matter of Life(time) and Death", ACS Catal., 2018, 8, 8597-8599.

The three “virtues” of catalyst performance are activity, selectivity, and productivity (the last of these being related to catalyst lifetime). In Murzin’s textbook “Engineering Catalysis”,(1) they are called the “trinity of catalysis”. Activity is usually the metric of highest interest to academic researchers (although in practice it is often straightforward to compensate for low activity simply by increasing the amount of catalyst in the reactor and/or the reaction temperature). For industry practitioners, the selectivity and productivity metrics are often more important. Low selectivity implies wasted raw materials and the need for costly, energy-intensive product separations, while a need for frequent catalyst replacement/regeneration results in lost production time. Loss of activity is not the only reason to perform catalyst change-out: increased pressure drop due to fines generation or catalyst breakage may necessitate replacement long before a decline in catalyst performance requires it.

Superlative Scientific Writing

Susannah L. Scott and Christopher W. Jones. "Superlative Scientific Writing", ACS Catal. 2017, 7, 2218-2219.

Publication in peer-reviewed journals serves to disseminate scientific findings, while certifying them (via peer-review) and archiving them for future use.(1) It also documents authors’ claims for the precedence of their ideas and provides crucial recognition that advances their careers. In 2014, there were over 34 000 peer-reviewed academic journals.(1) Nevertheless, the demand for space, particularly in the leading journals of each field, has become intense: the number of individual authors vying for this space worldwide is increasing at a rate of about 3% per year. The total number of published research articles (as recorded by Scopus) is growing even faster: over 6% per year, based on the increase from 1.3 million to 2.4 million in the decade from 2003 to 2013.(2) To manage the deluge, many selective journals, including ACS Catalysis, have adopted an editorial triage process to identify papers that are likely to fare well in their peer-review process. Referees are then asked to assess the novelty or potential impact, in addition to the scientific soundness, of the work that is selected for review. In this hypercompetitive environment, how are authors to increase their chances of having their papers reviewed and eventually published?
