A method for preparing flaky TiO 2 /g-C 3 N 4 heterojunction in one step, comprising the following steps: (1) adding acetylacetone and tetrabutyl titanate in sequence to absolute ethanol to obtain solution A; ( 2) Add polyvinylpyrrolidone to solution A, and dissolve completely to obtain solution B; (3) add an appropriate amount of melamine powder to solution B, and obtain mixed solution C after completely dissolving; (4) put mixed solution C into a syringe, Electrospinning is carried out under certain conditions, and the spinning product is collected by a stainless steel plate; (5) After the spinning product is dried, it is roasted at 550° C. for 4 hours in an air atmosphere. The invention has the advantages of simple and fast method, low cost, small diameter of product fiber and large specific surface area, and is widely used in photocatalytic hydrogen production and pollutant degradation. |
