The invention discloses a TiO2 coating with photocatalytic function and a preparation method. The TiO 2 coating includes a substrate, a binder coating provided on the substrate and a nano-TiO 2 coating provided on the adhesive coating; the nano-TiO 2 coating includes nano-TiO 2 particles and solvent. The TiO 2 coating with photocatalytic function solves the problems of agglomeration and weak bonding when nano TiO 2 is dispersed, and at the same time overcomes the problem that TiO 2 is covered by the binder due to the use of the binder, which affects the catalytic activity. , the TiO 2 coating prepared by the invention has uniform coating, stable and controllable TiO 2 loading, and firm adhesion with the substrate, which overcomes the shortcomings of the prior art. In addition, the preparation method is simple, time-consuming and scalable. The photocatalytic reaction induced by ultraviolet light has high catalytic activity, and the TiO coating has broad application prospects in photocatalytic fields such as water treatment, air purification, sterilization and antibacterial. |
