Advanced Science, Volume 13, Issue 13, 3 March 2026.Various spillover‐mediated electrocatalytic reactions, such as hydrogen and oxygen evolution, carbon dioxide and nitrogen reduction, and methanol oxidization reactions, are systematically summarized. Abstract Spillover phenomenon, which is characterized by the dynamic migration of active species across catalyst surfaces, provides a promising avenue to ...

Carbon Neutralization, Volume 5, Issue 2, March 2026.The co‐doping of N and S significantly strengthens the metal‐support interaction of Pt@N,S‐HCN, thereby promoting the rearrangement of Pt electron structures (Pt°→Ptx+) and increasing the density of Pt active sites. This enhances the adsorption affinity of Pt active centers for OH intermediates and reduces the binding strength of CO, ultimately ...

DMFC: Galvanic or electrolytic cell?
Electrochemistry Communications, 2006 We report measurements of local current distribution in a direct methanol fuel cell with single straight channels and segmented electrodes. The experiments directly confirm the existence of a bifunctional regime of DMFC operation: at low air flow rate the segments located close to the inlet of the oxygen channel generate current (galvanic domain ...
