  • High-entropy alloys are promising electrocatalysts for multistep and tandem reactions, yet its mechanism remains unclear. Here, the authors address this challenge by using in-situ XAS to reveal the multi-site hydrogen evolution mechanisms on high-entropy metallenes in wide pH electrolytes.

  • Selective CO₂-to-liquid conversion remains a major challenge due to inertness of CO₂. This work designs Pd nanoneedles with bent Pd–Pd bonds, enabling >99% selective formic acid production under mild conditions by enhancing CO₂ activation.

  • While noble metals can be active electrocatalysts for producing renewable H2, there are relatively few works examining osmium materials. Here, the authors prepare boron-doped osmium aerogels for H2 evolution electrocatalysis plus examine the mechanism using computational and in situ characterization.

  • The Zhang-Rice singlet is known for the superconductivity of high-temperature superconductors cuprate but is rarely studied for an electrochemical catalyst. Here, the authors use operando spectroscopic tools and observe Cu active site evolves into high-valent CuO4 geometry with Cu3+ active species, so-called Zhang-Rice singlet state, during oxygen evolution reaction.
