Preparation of Ir–Cu/C nanosheets for the oxygen evolution reaction by room temperature plasma carbonization

Abstract

Ir-Cu/C nanosheets with a thickness of about 2 nm were prepared using Ar plasma carbonization and reduction at room temperature. The obtained Ir-Cu/C catalyst, composed of single atom Ir-doped Cu...

Laser-induced immobilization of an amorphous iron-phosphate/Fe3O4 composite on nickel foam for efficient water oxidation

“…5 Although scarce and expensive Ir- and Ru-based oxides can be used to reduce the energy barriers for the OER, their wide applications are limited. 6–8 Therefore, developing efficient and earth-abundant transition-metal-based electrocatalysts, such as metal sulfides, 9,10 phosphides, 11 oxides, 12,13 etc. , to enhance the OER performance is urgently needed.…”
