Abstract
Many researchers have made efforts on designing and synthesizing catalytic active site as well as deciphering how exactly they catalyze the reaction to obtain electrocatalysts with superior water splitting activity. However, the development of high-performance dual-functional non-precious metal electrocatalysts for Hydrogen Evolution Reaction (HER) and Oxygen Evolution Reaction (OER) remains challenging. In this study, CoFe undergoes in a one-step phosphorylation reaction converted to Fe2P, CoP2 and Co2P, abbreviated as heterojunction metal phosphide (CoFeP). The Co/Fe ratio can be flexibly adjusted by controlling the content of Co in the synthesis process, which results in CoFeP with different morphologies. Benefiting from the porous structure and higher catalytic active sites, the Co-0.0032-FeP presents a lower overpotential of 127 mV and 266 mV for HER and OER of 10 mA cm−2 in a KOH solution, respectively. In addition, the low Tafel Slope and stable current density of Co-0.0032-FeP indicate fast kinetics and high stability in the HER.
