The invention discloses a preparation method of a poly(3-hexylthiophene) (P3HT)/metal-modified Sn3O4 nano composite photocatalytic material. According to the method, a composite photocatalyst materialis obtained by loading and dispersing a metal-modified Sn3O4 semiconductor heterojunction in poly(3-hexylthiophene) in the form of chemical bond complexation; wherein the metal-modified Sn3O4 is prepared by loading Sn3O4 with metal nanoparticles of a one-component mental or a multi-component alloy with a plasmon resonance effect such as Pt, Au, Ag, Cu and the like, respectively. According to theinvention, the visible light photocatalytic redox properties of Sn3O4, the plasmon resonance effect of metal nanoparticles, the electrical conductivity of poly(3-hexylthiophene) and a heterojunction structure with chemical bonding among the three components are utilized to fully enhance the photo-generated electrons-hole separation rate of the nano composite photocatalytic material in a photocatalytic reaction, so that the
