Abstract Electrochemical reduction of nitrate to ammonia (NO 3 RR) has been recognized as an appealing approach realize both sustainable NH production and waste removal. Herein, from the perspective Lewis acid‐base interaction, a single‐atom Fe‐doped V 2 O 5 (Fe‐V ) catalyst enriched is designed with acid sites, which present maximum ‐Faradaic efficiency 97.1% corresponding yield 12.5 mg h −1 cm −2 at –0.7 versus RHE. Mechanistic studies based on theoretical calculations operando spectroscopic characterizations identify creation Fe‐V pairs , can synergetically activate NO − promote hydrogenation energetics, restrain hydrogen evolution, leading enhanced RR activity selectivity.

Abstract With the development of renewable energy systems, clean hydrogen is burgeoning as an optimal alternative to fossil fuels, in which its application promising retarding global and environmental crisis. The evolution reaction (HER), capable producing high‐purity rapidly electrocatalytic water splitting, has received much attention. Abundant research about HER been done, focusing on advanced electrocatalyst design with high efficiency robust stability. As potential catalysts, metal nanoclusters (MNCs) have studied extensively. They are composed several a hundred atoms, sizes being comparable Fermi wavelength electrons, that is, < 2.0 nm. Different from atoms/nanoparticles, they exhibit unique catalytic properties due their quantum size effect low‐coordination environment. In this review, activity‐enhancing approaches MNCs applied electrocatalysis mainly summarized. Furthermore, recent progress classified different stabilization strategies, freestanding MNCs, organic, carbon supports, introduced. Finally, current challenges deficiencies these for prospected.

Iridium (Ir)-based catalysts are highly efficient for the anodic oxygen evolution reaction (OER) due to high stability and anti-corrosion ability in strong acid electrolyte. Recently, intensive attention has been directed novel, efficient, low-cost Ir-based overcome challenges of their application water electrolysis technique. To make a comprehensive understanding recently developed catalytic properties, mechanism promotion principles were discussed OER condition aimed proton exchange membrane electrolyzer (PEMWE) this review. The mechanisms adsorbate lattice first presented easy mechanism; brief perspective analysis from aspects geometric effect, electronic synergistic defect engineering, support effect was concluded. Then, latest progress practical introduced detail, which classified into varied composition Ir catalyst terms alloys, hetero-element doping, perovskite, pyrochlore, heterostructure, core–shell structure, supported catalysts. Finally, problems faced by current acidic electrolyte put forward. It is concluded that with low loading should be future, paid probing structural performance correlation, real PEMWE devices.Hopefully, effort can helpful catalysis OER, instructive novel design fabrication.

The development of efficient electrochemical seawater splitting catalysts for large-scale hydrogen production is great importance. In this work, we report an amorphous Co-Mo-B film on Ni foam (Co-Mo-B/NF) via a facile one-step electrodeposition process. Such Co-Mo-B/NF possesses superior activity with small overpotential 199 mV at 100 mA cm−2 evolution reaction in alkaline seawater. Notably, also maintains excellent stability least 24 h under electrolysis.

We have achieved the synthesis of dual-metal single atoms and atomic clusters that co-anchor on a highly graphitic carbon support. The catalyst comprises Ni4 (and Fe4) nanoclusters located adjacent to corresponding NiN4 FeN4) single-atom sites, which is verified by systematic X-ray absorption characterization density functional theory calculations. A distinct cooperation between Fe4 (Ni4) FeN4 (NiN4) sites optimizes adsorption energy reaction intermediates reduces barrier potential-determining steps. This exhibits enhanced oxygen reduction evolution activity long-cycle stability compared counterparts without commercial Pt/C. fabricated Zn-air batteries deliver high power long-term cyclability, demonstrating their prospects in storage device applications.
