  • On the threshold of the New Year we think back to the past 12 months and provide a few highlights.

  • Atomically dispersed and nitrogen-coordinated single iron site catalysts hold great promise to replace platinum for proton-exchange membrane fuel cells, but they suffer from significant performance loss. Now, solving the conundrum to distinguish durable and non-durable FeN4 active sites can guide high-performance catalyst design.

  • Despite over a century of research to understand heterogeneous electrocatalysis, the precise mechanisms of action remain poorly understood. Now, it is proposed that the oxygen evolution reaction on IrOx is driven by changes in the redox state of the Ir–O active sites, rather than by changes in the interfacial electric field.

  • 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.
