Rational design of FeOx-MoP@MWCNT composite electrocatalysts toward efficient overall water splitting

Abstract

Herein, a series of FeO_x-MoP@MWCNT composite electrocatalysts was designed and prepared to investigate the influence of the content of FeO_x on the water splitting performance. The optimized FeO_x-MoP@MWCNTs-2 exhibits excellent hydrogen and oxygen evolution reaction activity while a cell voltage of 1.51 V with outstanding stability is attained, attributed to the synergistic effect of each component, as evidenced by the experimental and density functional theory results. The observed electrocatalytic activity outperforms current state-of-the-art non-precious metal electrocatalysts.
