Abstract: A method for hydrothermal synthesis of 3D Bi4MoO9/TiO2 nanostructure heterojunction includes the following step: adding Bi(NO3)3.5H2O into distilled water to form a white turbid liquid, and adding an alkaline solution into the white turbid liquid until a potential of hydrogen value of the white turbid liquid is between 3 and 7, thereby obtaining a suspension A; adding TiO2 nanospheres into the suspension A to form a mixed suspension C; adding Na2MoO4.2H2O into distilled water to be dissolved to obtaining a Na2MoO4 solution; adding the Na2MoO4 solution into the mixed suspension C to form a mixture, and adding an alkaline solution into the mixture until a potential of hydrogen value of the mixture is greater than 7, thereby obtaining a mixed suspension D; transferring the mixed suspension D to a closed vessel for a hydrothermal reaction to obtain a hydrothermal synthesis product; and washing and drying the hydrothermal synthesis product.
