Self-supported Al-doped cobalt phosphide nanosheets grown on three-dimensional Ni foam for highly efficient water reduction and oxidation

Abstract

Al-doped CoP nanosheets self-supported on Ni foam are shown to be an efficient bifunctional electrocatalyst for long-time overall water splitting.

Self-supported Ni2P nanosheets on low-cost three-dimensional Fe foam as a novel electrocatalyst for efficient water oxidation

“…More recently, our group reported FeNiP solid solution as a highly efficient catalyst for OER with a very low catalytic overpotential for OER (180 mV to reach 10 mA/cm 2 ) [29] . A few novel self-supported metal phosphide catalysts on Ni or C substrates have been reported for OER with good catalytic activities in the literature [30][31][32][33][34] .…”

Ce‐Doped Ordered Mesoporous Cobalt Ferrite Phosphides as Robust Catalysts for Water Oxidation

“…[17][18][19] To increase the performance of electrocatalysts, doping suitable components is considered as an efficient way to regulate the electronic structure and optimize the structure morphology. [20][21][22] Ce with variable valence exhibits good conductivity and high oxygen storagea bility,w hich offerst he opportunity to generate strong electron coupling with other materials,t hus enhancing the electrocatalytic performance for OER. [23][24][25] For example, Gao and co-workersd emonstrated that CeO 2 doped in the NiO clusters hows excellent performance for OER owing to the promoted oxygen storage ability and modulated electronic structure of the active sites.…”

Engineering Electronic Structures of Nickel Cobalt Phosphide via Iron Doping for Efficient Overall Water Splitting

“…Meanwhile, metal doping has been demonstrated to be an efficient strategy to enhance the OER/HER catalytic activities of TMPs by recent studies [17,18] . For instance, Hu and co‐authors reported that Al doping could significantly improve the OER/HER intrinsic activities of CoP in alkaline electrolytes [19] . Song and co‐authors showed that the Cu dopant could tune the electronic structure of CoP, thus remarkably improving the water splitting intrinsic catalytic activity [20] .…”
