An electrocatalyst composed of CoNi(hydroxide) nanosheets and flower-like CoFe2O4 particles with multiple porous structure is successfully deposited on nickel foam and applied for overall water splitting.
Efficient and low-cost sea coral-like NiCo2O4@(Ni, Co)OOH heterojunction catalysts meet the high current density requirements for industrial water electrolysis applications.
A synergistic strategy of interface engineering and surface modification is efficient to construct a promising bifunctional electrocatalyst for enhanced electrocatalytic water splitting.
