Abstract Practical electrochemical water splitting requires cost‐effective electrodes capable of steadily working at high output, leading to the challenges for efficient and stable oxygen evolution reaction (OER). Herein, by simply using conductive FeS microsheet arrays vertically pre‐grown on iron foam (FeS/IF) as both substrate source in situ form aligned NiFe(OH) x nanosheets arrays, a hierarchical electrode with nano/micro sheet‐on‐sheet structure (NiFe(OH) /FeS/IF) can be readily...
Nitrogen-doped carbon materials (N-Cmat ) are emerging as low-cost metal-free electrocatalysts for the electrochemical CO2 reduction reaction (CO2 RR), although activities still unsatisfactory and genuine active site is under debate. We demonstrate that RR to CO preferentially takes place on pyridinic N rather than pyrrolic using phthalocyanine (Pc) porphyrin with well-defined N-Cmat configurations molecular model catalysts. Systematic experiments theoretic calculations further reveal...
Strong metal–support interaction (SMSI), commonly happening between metal and oxide support, has drawn significant attention in heterogeneous catalysis due to its capability of enhancing the activity stability catalysts. Herein, strong carbon supports is discovered significantly boost performance for electrocatalytic CO2 reduction reaction (CO2RR). A molecular engineering strategy designed develop undoped, N-doped, S-doped, N,S-codoped porous with similar physical properties (denoted as C,...
Highly efficient and stable bifunctional electrocatalysts for oxygen reduction evolution are essential aqueous rechargeable Zn-air batteries, which require highly active sites as well delicate structural design increasing effective facilitating mass/electron transfer. Herein, a scalable facile self-catalyzed growth strategy is developed to integrate Co-N-C with 3D brush-like nanostructure, achieving nanobrushes Co,N-codoped carbon nanotube branches grown on nanoparticle assembled nanowire...
ConspectusTremendous efforts have shown that the precise control of electrocatalyst structure and morphology can boost their catalytic performance toward diverse important reactions such as oxygen reduction/evolution (ORR/OER), hydrogen oxidation/evolution reaction (HOR/HER), carbon dioxide/nitrogen reduction (CO2RR/NRR), etc. The physical chemical confined syntheses witnessed success in manipulating catalyst features from macroscopic to atomic level deal with various application demands.In...

A metal sulfide and carbonate hydroxide heterostructure featuring a unique “nanoparticle-in-nanosheet” structure with abundant accessible hetero-interfaces is developed for efficient robust water oxidation.
The importance of charge diffusion in electrocatalysts is shown by regulating the thickness CoFe hydroxide nanosheets on graphene. few-layer allow effective diffusion, enabling a 2000 mA cm<sup>−2</sup> output at only 1.507 V cost near-industrial conditions.
