Abstract:

Transition metal phosphate has attracted the attention of researchers in the field of electrolytic water because of its advantages of safety, cleanliness, low cost and high efficiency. Phosphate groups in phosphate have unique atomic geometric structure, strong coordination and various orientations, which are beneficial to stabilize the middle valence state of transition metals and accelerate proton conduction rate. However, its poor conductivity and low porosity have prompted researchers to explore and design more efficient transition metal phosphate electrocatalysts. Although researchers have invested a lot of time and energy, there are still many problems to be solved in the efficient development and utilization of transition metal phosphate electrocatalysts. In this paper, combined with the latest research progress of transition metal phosphate electrocatalysts, the development and design strategies of phosphate by researchers in recent years are introduced from the aspects of morphology control, defect engineering and interface engineering. At the same time, the opportunities and challenges faced by this kind of catalyst in the future material field are discussed from the aspects of scientific research and practical application.
