长期以来,过渡金属磷酸盐因其安全清洁、低廉高效的优点在电解水催化剂领域备受研究者们的关注。磷酸盐中的磷酸基团具有独特的原子几何结构、较强的协调性以及多种取向性,使其有利于稳定过渡金属的中间价态并加速质子传导速率。然而其电导率差、孔隙率低的缺点则促使研究者们探究设计更加高效的过渡金属磷酸盐电催化剂。虽然科研人员为此投入了大量的时间和精力,在过渡金属磷酸盐电催化剂高效开发利用上仍有许多问题亟待解决。在此,结合过渡金属磷酸盐电催化剂近10年的最新研究进展,重点从形貌调控、缺陷工程和界面工程等几方面介绍了近几年科研工作者对于磷酸盐的开发设计策略。同时,从科学研究及实际应用方面讨论了该类催化剂在未来材料领域需要面对的机遇与挑战。

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.
