Here we propose a Ti3C2Tx MXene-based synthetic method for constructing Co2P/Ti3C2Tx, Fe2P/Ti3C2Tx and Co2P/Fe2P multiple heterojunctions (labeled as CoFe-P@MXene) by using strong electrostatic adsorption-electrodeposition-low temperature phosphorization. The obtained CoFe-P@MXene possesses abundant three-dimensional porous structures and inherits the high conductivity of MXene. Experiment results and density functional theory calculations indicate that the formation of multi-heterojunctions between transition metal phosphides and Ti3C2Tx MXene can modulate the electronic structure of active sites Co and Fe, alter the d-band center, and thereby optimize the adsorption energy of oxygen-containing intermediates on the active sites. Additionally, the excellent nanoporous structure constructed promotes the penetration of the electrolyte and the release of the product. Thus, The CoFe-P@MXene-based electrocatalyst exhibits excellent OER catalytic performance at both low current densities and industrial-scale current densities, with remarkable low overpotentials of 215 mV at 20 mA cm−2 and 328 mV at 1000 mA cm−2 in 1 M KOH solution, respectively.
