[0028] The invention provides a method for preparing a silver-modified titanium dioxide-calcium titanate crystal film material, comprising the following steps:
[0029] Step 1, preparing monodisperse microsphere colloidal crystal film template;
[0030] In step 1, the microspheres in the monodisperse microsphere colloidal crystal film template can be polystyrene (PS) microspheres or polymethylmethacrylate (PMMA) microspheres;
[0031] The specific preparation steps are as follows: dilute the microsphere colloidal crystal emulsion to a mass concentration of 1wt%, then perform ultrasonic dispersion, then evaporate and self-assemble on the FTO conductive glass at a temperature of 55°C, and finally obtain a monodisperse microsphere colloidal crystal thin film template;
[0032] Step 2, preparing titanium dioxide sol, the specific scheme is:
[0033] Mix the titanium-containing compound with alcohol, deionized water, and 36.0-38.0% hydrochloric acid at a volume ratio of 5:5:2:1 to...
Embodiment 1
[0042] Step 1, prepare monodisperse microsphere colloidal crystal film template: use dispersion polymerization to prepare monodisperse PS microspheres, dilute the obtained PS emulsion to 1wt%, take 5mL of the diluted emulsion, put it into a 10mL glass culture bottle, Insert the FTO conductive glass vertically into the culture bottle, put it in an oven, evaporate and self-assemble at 55°C, and obtain the PS thin film template.
[0043] Step 2, preparing titanium dioxide sol: uniformly mix isopropyl titanate with ethanol, deionized water, and hydrochloric acid at a volume ratio of 5:5:2:1 to obtain titanium dioxide sol.
[0044] Step 3, place the PS colloidal crystal film template in step 1 in the titanium dioxide sol in step 2, then place it in a vacuum oven and keep it at a vacuum degree of 20.133kPa for 30min, and finally place the PS colloid filled with titanium dioxide sol The crystal thin film template was taken out and placed at room temperature for 12h;
[0045] Step 4:...
