Abstract

The process of electrocatalytic water splitting is a promising technology for the generation of green hydrogen, despite challenges such as low electrical conductivity and limited activity in the application of the CoFe2O4 catalyst. This study presents the development of a novel bifunctional P-CoFe2O4/CNTs catalyst with enhanced catalytic performance through the combination of heterojunction construction and heteroatom doping strategies. The enhanced electrical conductivity and increased active sites of P-CoFe2O4/CNTs, resulting from the synergistic effect of the unique heterojunction structure and oxygen vacancies induced by P-doping, lead to exceptional hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) performances in acidic and alkaline environments, respectively. The catalyst design presented in this study has the potential to inspire the development of novel bifunctional catalysts with superior catalytic activity.
