The preparation method is as follows: dispersing selenium powder I and polyvinylpyrrolidone in water, then adding hydrazine hydrate and stannous chloride in sequence, mixing and stirring, and then performing hydrothermal reaction to obtain SnSe nanosheets; dispersing the SnSe nanosheets in triethylene glycol, then adding indium tetrachloride and selenium powder II in sequence, mixing and stirring, and then performing solvothermal reaction, and the binary heterojunction nanomaterial is obtained. The binary heterojunction nanomaterial has excellent catalytic performance and high cycle stability, and has a good removal effect on organic and inorganic pollutants. The preparation method is simple, low in cost and convenient to operate.
