Ruthenium (Ru)‐based catalysts have displayed compelling hydrogen evolution activities, which hold the promising potential to substitute platinum in alkaline H2‐evolution. In the challenging alkaline electrolytes, the water‐dissociation process involves multistep reactions, while the profound origin and intrinsic factors of diverse Ru species on water‐dissociation pathways and reaction principles...
Advanced metal–sulfur batteries (MSBs) are regarded as promising next‐generation energy storage devices. Recently, engineering polysulfide redox catalysts (PSRCs) to stabilize and catalytically convert polysulfide intermediates is proposed as an effective strategy to address the grand challenge of “shuttle effects” in the cathode. Therefore, modulating the bond interactions and interface microenvironments...
Developing efficient, durable, and low‐cost earth‐abundant elements‐based oxygen evolution reaction (OER) catalysts by rapid and scalable strategies is of great importance for future sustainable electrochemical hydrogen production. The earth‐abundant high‐valency metals, especially vanadium, can modulate the electronic structure of 3d metal oxides and oxyhydroxides and offer the active sites near‐optimal...
