    Molecular catalysts anchored on electrode surfaces are commonly assumed to behave similarly to their homogeneous counterparts. Under some conditions, however, they can behave like metallic electrodes. Now, the underlying phenomena behind this fresh paradigm in heterogeneous electrocatalysis are uncovered.

    Cu-based single atom catalysts can convert CO2 into multi-carbon products, however, the assignment of active sites needs great caution. In this comment, the authors discuss the transient Cu cluster formation as active sites and emphasise the need for operando characterisation in mechanistic study.

    Ring-forming reactions are at the heart of organic synthesis. Now, phenylene rings are synthesized from two isopropyl moieties on a gold surface. Resolving the intermediates of this (3+3) cycloaromatization reaction with atomic force microscopy offers mechanistic insight into the dimerization process.

    The discovery of robust and efficient water oxidation catalysts based on first-row transition metal complexes is still a challenge. Here, we describe the underlying chemistry related to the deactivation pathways of first-row transition metal complexes and put forward a series of principles and basic checks to enable the development of robust catalysts.

    A new class of catalysts based on ternary ruthenium complex hydrides are developed for low-temperature ammonia synthesis. They support a non-dissociative reaction path for dinitrogen reduction, in which lithium or barium cations stabilize the NxHy intermediates and the electron- and H-rich [RuH6]4– anionic centres facilitate an energetically balanced multi-step reaction for ammonia synthesis.
