The hydrogen evolution reaction (HER) is one of the most prominent electrocatalytic reactions green energy transition. However, kinetics across materials and electrolyte pH impact coverage at high current densities remain poorly understood. Here, we study HER over a large set nanoparticle catalysts in industrially relevant acidic alkaline membrane electrode assemblies that are only operated with pure water humidified gases. We discover distinct kinetic fingerprints between iron triad (Fe, Ni, Co), coinage (Au, Cu, Ag), platinum group metals (Ir, Pt, Pd, Rh). Importantly, applied bias changes not activation (EA) but also pre-exponential factor (A). interpret these as entropic interfacial solvent differ acid base on surface due to changing coverage. Finally, observe anions can induce Butler–Volmer behavior for acid. Our results provide new foundation understand and, more broadly, highlight pressing need update common understanding basic concepts field electrocatalysis.

Electrocatalysis is one of the principal pathways for transition to sustainable chemistry, promising greater energy efficiency and reduced emissions. As field has grown, our theoretical understanding matured. The influence applied potential on reactivity developed from first-order predictions based Nernst equation implicit inclusion second-order effects including interaction reacting species with interfacial electric field. In this review, we explore these non-Nernstian in electrocatalysis, aiming both understand exploit them through theory computation. We summarize critical distinction between Nernstian outline strategies address latter studies. Subsequently, examine specific energetic contributions capacitive faradaic processes separately. also underscore importance considering catalyst screening mechanistic analysis. Finally, provide suggestions how experimentally unravel effects, offering insights into practical approaches advancing

Decentralized water treatment technologies, designed to align with the specific characteristics of source and requirements user, are gaining prominence due their cost energy-saving advantages over traditional centralized systems. The application chemical via heterogeneous advanced oxidation processes using peroxide (O-O) represents a potentially attractive option. These serve initiate redox at solid-water interface. Nevertheless, mechanism exemplified by typical Fenton-like persulfate-based oxidation, in which electron transfer dominates, is almost universally accepted. Here, we present experimental results that challenge this view. At solid-liquid interface, it demonstrated protons thermodynamically coupled electrons. In situ quantitative titration provides direct evidence coupling ratio transferred electrons 1:1. Comprehensive thermodynamic analyses further demonstrate net proton-coupled occurs, both entering cycle. findings will inform future developments O-O activation enabling more efficient activity tight

Electrochemical CO 2 reduction (CO R) to value‐added products using renewable electricity offers a promising approach toward achieving carbon neutrality. Among various electrocatalysts, molecular catalysts, particularly transition metal complexes, stand out due the high selectivity for single specific and desirable tunability, enabling rational optimization of catalytic performance. However, their practical application is hindered by low operating current densities challenges in catalyst recycling. To address these limitations, immobilizing catalysts on electrode surfaces has emerged as an effective strategy integrating selective into heterogeneous catalysis. This mini review focuses distinct category heterogenized catalysts—those molecularly dispersed supported substrates or surfaces‐which exhibit remarkable activity at single‐molecule level ability drive deep (beyond two electrons) under certain conditions. Recent progress this field comprehensively discussed, emphasizing critical impacts molecule‐level dispersion catalyst‐support interactions electronic properties, multi‐electron transfer kinetics, overall Moreover, overview potential applications beyond electrochemical R provided end. aims offer valuable insights future design efficient scalable electrocatalysts sustainable conversion.
