The invention discloses a preparing method and application of NiPS3 nanosheets of a self-supporting structure, and belongs to the technical field of preparation of nanometer materials and preparationof clean energy. The preparing method aims at solving the problems that when NiPS3 serves as an HER catalyst, the superficial area is small, and the temperature required in the preparing process is high. The preparing method comprises the steps of 1, conducting ultrasonic cleaning on carbon cloth; 2, mixing red phosphorus powder and sublimed sulfur powder, and obtaining a phosphorus and sulfur powder mixture after grinding; 3, adding nickel salt, urea and ammonium fluoride into ultrapure water for stirring and dissolution to obtain a reaction solution; 4, soaking the carbon cloth in the reaction solution for a hydrothermal reaction; 5, pouring the phosphorus and sulfur powder mixture into an open reactor, putting the open reaction and a precursor together into a corundum boat, firstly, adding the phosphorus and sulfur powder mixture to be fused, then conducting sublimation, and carrying out a reaction between phosphorus and sulfur steam and the precursor at high temperature. Accordingto the preparing method, the synthesis temperature is low, an NiPS3 nanosheet catalyst and a conductive substrate are compounded to be directly used as an HER electrode, and subsequent treatment is not needed.
