  • This Comment articulates simple metrics that can guide early catalysis research to make the manufacture of fuels and chemicals sustainable and affordable. These metrics cover resource efficiency (waste/CO2 production, selectivity) as well as conversion performances that look at different aspects of the process.

  • The Fischer–Tropsch product, water, is regularly hypothesized to be the driving force for catalyst deactivation. Cobalt nanoparticles may be oxidized to CoO, form mixed-metal oxides with supports, or sinter to larger particles. This Comment discusses the feasibility of these deactivation pathways, highlighting the importance of in situ characterization.

  • Considerable research achievements were made to address the plastic crisis using biotechnology, but this is still limited to polyesters. This Comment aims to clarify important aspects related to myths and realities about plastic biodegradation and suggests distinct strategies for a bio-based circular plastic economy in the future.

  • Two different types of H2O2 selectivity are reported for the electrochemical synthesis of H2O2: molar fraction selectivity and Faradaic selectivity. Here we revisit their definitions and discuss the best way to report H2O2 selectivity, which can help to avoid misunderstandings or unfair performance comparisons in this growing field.

  • Catalysis is essential in the automotive and transportation sectors to target the United Nations sustainable development goals for climate change and the environment. To comply with both the ambitious United Nations goals and step-by-step stringent emission regulations, innovative and economically viable catalytic systems will be a key element in meeting these challenges.

  • For the foreseeable future, we will continue to rely on the internal combustion engine for mobility of people and goods. The ubiquitous three-way catalyst does not work below 350 °C, with appreciable O2, nor does it control soot. Low temperature catalysis, chemical trapping and filtration will grow in need, and represent research opportunities.

  • Radical intermediates are key species in many chemical transformations. Recent advances have provided a new suite of selective radical alkylation reactions. This Comment highlights pioneering studies using alkyl amines that act as radical precursors in a number of catalytic processes by their conversion to alkylpyridinium salts.
