The invention provides a method for preparing a silver-modified titanium dioxide-calcium titanate crystal thin film material. Immersion in vacuum, natural drying, and then calcining the colloidal crystal film template filled with titanium dioxide sol to obtain a titanium dioxide crystal film, which is placed in a mixed solution of alkaline calcium ions and silver ions in water and ethanol, and undergoes a hydrothermal reaction. And calcined in a nitrogen atmosphere to finally obtain a silver-modified titanium dioxide-calcium titanate crystal thin film. The silver-modified titanium dioxide-calcium titanate crystal thin film material prepared by the invention has high filling rate, complete pore structure and small shrinkage rate; compared with the traditional process, the preparation process is simple and the equipment requirements are low. |
