Low conductivity over a wide temperature region due to ultra‐slow ion migration dynamics is a key issue in the field of solid‐state electrolytes (SSE), which needs to be solved and improved. Covalent organic frameworks (COFs), a rapidly growing class of porous crystalline materials, emerge as a new research hotspot in the field of SSEs. This is due to their homogeneously dispersed sites and well‐defined...
Surface oxygen vacancies (Vo) regulation is an effective strategy to improve the electrochemical CO2 reduction reaction (CO2RR) performance by lowering the activation energy barrier of CO2; however, the lack of precise control over the local atomic structures severely hinders the large‐scale application of Vo‐activated electrocatalyst for CO2RR. Herein, an efficient strategy to facilitate CO2 activation...
The surface reconstruction of oxygen evolution reaction (OER) catalysts has been proven favorable for enhancing its catalytic activity. However, what is the active site and how to promote the active species generation remain unclear and are still under debate. Here, the in situ synthesis of CoNi incorporated Fe3N nanotubes (CoNi–Fe3N) on the iron foil through the anodization/electrodeposition/nitridation...
