Directing Ru-based acidic oxygen evolution catalysts toward a universal dual-site pathway

Yingjie Hu, Yongde Long, Baoguang Mao, Zeqiang Yu et autres

The oxide path mechanism offers vision possibility from kinetics for the anodic oxygen evolution reaction, yet its universal activation remains elusive due to the difficulty of constructing globally appropriate interatomic distances. Here, we address this challenge in the integrated-screened Y0.1Ir0.2Ru0.7Ox by precisely …

Decoupling Kinetically Coupled Steps via Hierarchical Relay Catalysis on High‐Entropy Alloy for Efficient Ammonia Decomposition

Fashuo Du, Guobin Lai, B C Liu, Dechen Wang et autres

ABSTRACT Ammonia (NH 3 ) is a promising hydrogen carrier owing to its high gravimetric hydrogen storage density (17.6 wt%), but its practical utilization is hindered by sluggish decomposition kinetics at moderate temperatures. For commonly used Ru‐based catalysts, the reaction remains constrained …
