The development of bimetallic catalysts is often hindered by the heavy workload of the classical trial-and-error method. Now, a distinct mechanism demonstrates that breaking down the net thermochemical reaction into the corresponding electrochemical half-reactions offers a facile approach to design bimetallic catalysts by analysing each putative half-reaction.

The lack of stability of critical raw material-free electrocatalysts during the oxygen evolution reaction in acidic electrolytes lies beneath the use of Ir-based electrocatalysts in polymeric water electrolysis. Here, a strategy to enhance γ-MnO₂ stability in acid is proposed. Theoretical and spectroscopic approaches reveal that increasing the fraction of O atoms in the appropriate position, namely O_pla, prevents Mn dissolution during water electrolysis.

Rhodium catalysts confined in zeolite pores exhibit high regioselectivity in the hydroformylation process of propene to high-value n-butanal, surpassing the performance of all heterogeneous and most homogeneous catalysts developed so far.

The use of data science tools in catalysis research has experienced a surge in the past 10–15 years. This Review provides a holistic overview and categorization of the field across the various approaches and subdisciplines in catalysis.

Crystalline materials’ properties are highly dependent on their size. Here authors report a general synthesis of ultrasmall (4–6 nm) and highly defective Zr/Hf-Metal Organic Frameworks nanoparticles that present enhanced peptide hydrolysis performance.

The poisoning of single-atom catalysts hampers their performance. Here, the authors propose Au nanoparticles as an antidote for poisoned Au single-atom catalysts, with trace addition shown to reinforce and sustain propylene epoxidation.

Typically thought of as inert and non-participating atoms, noble gasses adsorbed onto freshly cleaved single crystal surfaces enhance their electronic band structures, potentially creating more active heterogeneous catalysts.

A strategy for the precise and scalable synthesis of a series of M₁M₂ (where M is a metal ion) heteronuclear dual-atom catalysts (DACs) is proposed. Photoinduced electron accumulation at the M₁ sites results in the capture and reduction of M₂ cations close to the M₁ sites to generate DACs with high purity.
