The invention discloses a morphology-controllable sulfur-functionalized metal organic framework catalytic material and a preparation method and application thereof.Thiophene-2, 5-dicarboxylic acid serves as a ligand of the catalytic material, bismuth salt serves as a metal source of the catalytic material, and the MOFs material has different morphologies including a micron flower ball shape, a cobweb shape and a micron flower shape by adjusting the proportion of metal to the ligand. According to the invention, thiophene-2, 5-dicarboxylic acid is used as an organic ligand containing S atoms, bismuth salt is used as a metal source to prepare a series of S-MOFs materials, the performance of a cobweb-shaped catalytic material is obviously improved compared with the performance of other morphologies, and meanwhile, the preparation experiment process is simple; bi-TDC with different proportions of ligands to metals shows different ultrasonic-light synergistic catalytic activities; and S atoms are doped, so that the
