Cu-based catalysts have been widely explored for the electrochemical nitrate reduction reaction (NO3RR), while intrinsic activity and selectivity of Cu metal NO3RR remain ambiguous, preventing a genuine comparison performance. Here we use polycrystalline foils benchmarking elucidate impact often overlooked factors on NO3RR, including facet exposure, concentration, electrode surface area. An electropolished foil exhibits higher to NH3 than wet-etched foil, benefiting from greater exposure...
Electrochemical nitrate reduction reaction (NO3RR) provides a promising route for the denitrification of wastewater and sustainable NH3 production but requires active selective electrocatalysts. Here, we demonstrate rigorous design tandem electrocatalyst efficient conversion NO3– to NH3. Based on screening components, catalyst coupling Cu Co(OH)2 with an optimal ratio architecture was developed promote balance activities sequential NO3RR steps different sites. Compared counterpart catalysts...
Many electrochemical reactions for the development of renewable energy technologies are gas-evolving reactions, where electrocatalytic performance is susceptible to wetting properties catalyst microenvironment. Here, using N2H4 electro-oxidation N2 on carbon-supported Pt nanocatalysts as a model reaction, we controlled microenvironment oxygen-doped and fluorine-doped carbon supports make it more hydrophilic hydrophobic, respectively, elucidated effect reaction kinetics. The electrode with...
Abstract Electrocatalysis plays a key role in the development of renewable energy technologies. Along with design electrocatalysts, microenvironment around catalytic sites has received increasing attention because it affects distribution and mass transport reaction species impacts kinetics. In this Concept article, we highlight some mechanistic insights into effect on gas‐involving electrocatalytic reactions, including CO 2 reduction, 2‐electron oxygen hydrazine oxidation, demonstrating...
Electrochemical reduction of nitrate provides a sustainable route for the recycling waste to valuable ammonia when powered by electricity from renewable sources. Development such process requires efficient electrocatalysts that can facilitate high single-pass conversion dilute ammonia. Here we report Cu nanowire electrocatalyst was prepared growing nanowires with tunable morphology and density on foam substrate. Compared foam, created new catalytic sites greatly enhanced activity selectivity...
