The evolution and formation process of two‐dimensional metal‐organic frameworks (MOFs) primarily arise from the anisotropic growth of crystals, leading to variations in photocatalytic performance. It is crucial to achieve a synergistic combination of anisotropic electron transfer direction and dimension reduction strategies. In this study, a novel approach that effectively blocks crystal growth accretion...
Fe–N–C Catalysts
In article number 2207671, Jia Li, Jianguo Liu, and co‐workers develop a highly‐catalytic Fe–N–C catalyst with a power density of >1 w cm−2 and prolonged lifetime (>40 h) using a controllable and efficient N–C coating strategy. The authors investigate the correlation between coating thickness and electrochemical performance. They also identify the stability improvement mechanism...
The vigorous development of efficient platinum group metal‐free catalysts is considerably important to facilitate the universal application of proton exchange membrane fuel cells. Although nitrogen‐coordinated atomic iron intercalated in carbon matrix (Fe–N–C) catalysts exhibit promising catalytic activity, the performance in fuel cells, especially the short lifetime, remains an obstacle. Herein,...
Hydrogen produced using renewable electricity is considered the key to achieving a low‐carbon energy economy. However, the large‐scale application of electrochemical water splitting for hydrogen evolution currently requires expensive platinum‐based catalysts. Therefore, it is important to develop efficient and stable catalysts based on the rich reserves of transition metals as alternatives. In this...
Bifunctional oxygen electrocatalyst: A metal–amino acid complex is developed to prepare high‐performance mesoporous carbon electrocatalyst for both oxygen reduction and oxygen evolution reactions. Such prepared catalyst can be used to assemble rechargeable zinc–air batteries with excellent durability. This work represents a new route toward low‐cost, highly active, and durable bifunctional electrocatalysts...
