The exploitation of cheap and efficient electrocatalysts is the key to make energy‐related electrocatalytic techniques commercially viable. In recent years, transition metal phosphides (TMPs) electrocatalysts have gained a great deal of attention owing to their multifunctional active sites, tunable structure, and composition, as well as unique physicochemical properties. This review summarizes the up‐to‐date progress on TMPs in energy‐related electrocatalysis from diversified synthetic methods, ingenious‐modulated strategies, and novel applications. In order to set forth theory–structure–performance relationships upon TMPs, the corresponding reaction mechanisms, electrocatalytsts' structure/composition designs and desired electrochemical performance are jointly discussed, along with demonstrating their practical electrocatalytic applications in overall water splitting, metal–air batteries, lithium–sulfur batteries, etc. In the end, some underpinning issues and research orientations of TMPs toward efficient energy‐related electrocatalysis are briefly proposed.

Modulating and constructing interface engineering is an efficient strategy to enhance catalytic activity for water splitting. Herein, a hybrid nanoarray structure of V‐CoP@a‐CeO2, where “a” represents amorphous, integrated into carbon cloth is fabricated for water splitting. The synergy effect between V and CeO2 can increase the electron density of Co atoms at active sites, further optimizing the Gibbs free energy of H* adsorption energy (ΔGH*). Besides, V‐CoP@a‐CeO2 possesses lower water adsorption/dissociation energies, enabling accelerated reaction kinetics in alkaline media. As expected, the V‐CoP@a‐CeO2 exhibits superior performance toward the hydrogen evolution reaction and the oxygen evolution reaction. More importantly, a two‐electrode electrolyzer combined with an electrocatalyst of V‐CoP@ a‐CeO2 only demands that voltages of electrolytic cell are 1.56 and 1.71 V to achieve the current densities of 10 and 100 mA cm−2, respectively. This work provides guidance for the design or optimization of materials for water electrolysis and beyond.

The necessity for better water splitting requires speedy development of efficient catalysts with high activity, long-term stability, and cost effectiveness. In this work, a bifunctional catalyst originating from the interfacial assembly of a thin Mo,P-codoped Co layer (≈50 nm) shelled Co nanowire (Co-Mo-P/CoNWs) network is fabricated via a facile approach. The catalyst exhibits low overpotentials of 0.08 and 0.27 V to reach a current response of 20 mA cm −2 for the hydrogen evolution reaction and oxygen evolution reaction, respectively, together with long-term stability in 1.0 m KOH medium. The outstanding performance is further demonstrated by a Co-Mo-P/CoNWs-based electrolyzer, which enables a cell voltage of only 1.495 V to reach 10 mA cm −2 , superior to one derived from commercial (Pt/C + RuO 2 /C) as well as to various reports recently published elsewhere. It is recognized that the formation of multiactive centers together with the increased active site number caused by Mo and P dual doping synergistically promote both hydrogen and oxygen evolution performance. Such a hybrid material opens a new approach for developing efficient and cost-effective catalysts for water splitting application.
