The invention discloses a rare earth composite nano ceramic antibacterial material based on visible light photocatalysis. The rare earth composite nano ceramic antibacterial material is prepared from the following raw materials in parts by weight: 10 to 20 parts of Al2O3, 10 to 20 parts of ZrO2, 10 to 20 parts of WO3, 30 to 60 parts of HfOCl2. 8H2O, 0.5 to 1 part of nano TiO2, 15 to 30 parts of rare earth nitrate, 5 to 7 parts of Sr2SiO4: Eu < 2 + > fluorescent powder, 15 to 30 parts of monomer, 0.5 to 1 part of initiator, 0.5 to 1 part of dispersing agent, 0.5 to 1 part of cross-linking agent and 0.5 to 1 part of catalyst. The medium-entropy rare earth ceramic material is prepared by adding Al2O3, ZrO2, WO3, HfOCl2. 8H2O and rare earth nitrate, has the characteristics of high crystallinity and good solid solution effect, and has good antibacterial property in a dark environment, the antibacterial rate of escherichia coli is 99.9%, the antibacterial rate of staphylococcus aureus is 99.6%, and the excellent photocatalytic effect of nano TiO2 is utilized, so that the medium-entropy rare earth ceramic material has a good application prospect. The rare earth composite nano ceramic antibacterial material has photocatalytic activity under visible light, the added Sr2SiO4: Eu < 2 + > fluorescent powder can store energy under the visible light and convert the energy in a dark environment to emit strong visible light, and the antibacterial performance of the material under the dark condition is enhanced.
