The invention provides a method for producing hydrogen through piezoelectric-light synergistic catalytic decomposition of water by adopting a nickel modified carbon nitride catalyst, and belongs to the technical field of water decomposition catalysts. The catalyst is placed in deionized water to form suspension liquid, inert gas is introduced after vacuum treatment, then light energy and mechanical energy are applied, and water is decomposed to produce hydrogen. The symmetry of the crystal structure of the material is adjusted through nickel doping, the piezoelectricity is improved, and the separation efficiency of current carriers is improved, so that the performance of producing hydrogen by piezoelectric-light synergistic catalytic decomposition of water is enhanced. When the catalyst is under the action of mechanical energy and light energy, a piezoelectric electric field is generated in the catalyst, so that electron-hole pairs generated by light excitation are driven to be quickly separated, and more eff
