Abstract This study reports the synthesis of ultrafine NiFe‐layered double hydroxide (NiFe‐LDH) nanosheets, possessing a size range between 1.5 and 3.0 nm with thickness 0.6 nm. Abundant metal oxygen vacancies impart nanosheets semi‐metallic character, thus superior charge transfer properties electrochemical water oxidation performance overpotentials (η) 254 mV relative to monolayer LDH (η 280 mV) or bulk materials 320 at 10 mA cm −2 . These results are highly encouraging for future...
Harvesting solar energy for catalytic conversion of CO2 into valuable chemical fuels/feedstocks is an attractive yet challenging strategy to realize a sustainable carbon-cycle utilization. Homogeneous catalysts typically exhibit higher activity and selectivity as compared with heterogeneous counterparts, benefiting from their atomically dispersed sites versatile coordination structures. However, it still "black box" how the electronic structures dynamically evolve during reaction, forming...
Abstract The oxygen reduction reaction (ORR) plays a fundamental role in sustainable energy technologies. However, the creation of non‐precious metal electrocatalysts with high ORR activity and durability under all pH conditions is great significance but remains challenging. Herein, aim to overcome this challenge by creating Fe single atom catalyst on 2D defect‐containing nitrogen‐doped carbon support (Fe 1 /DNC) via microenvironment engineering strategy. Microkinetic modeling reveals that...
