[0080] (3) The preparation method provided by the present invention is simple, easy to operate, and the yield of the photocatalyst product is high;
[0081] (4) The method is environmentally friendly and has no environmental pollution.
Example
[0083] Examples 1-7
[0084] Accurately weigh 6mg of sodium tetraphenylborate, put it in a small dry and clean beaker, add 10mL of distilled water to dissolve it, then add 10.0g of urea that has been accurately weighed, and then add 10mL of distilled water to it to completely dissolve it. When heated to 80°C, put the beaker in a water bath. After the water evaporates, transfer the sample to a dry and clean crucible, place it in a box-type resistance furnace, and bake it at 550°C for 2h. After cooling, place it in a grind. Grind finely in a bowl to obtain CNB products.
[0085] Accurately weigh out seven samples of 0.4g of the above-mentioned CNB and place them in seven small dry and clean beakers, numbered 1, 2, 3, 4, 5, 6, and 7, then accurately weigh out seven ZrO samples of different masses. 2 , The masses are respectively 0.0040g, 0.0030g, 0.0020g, 0.0010g, 0.0004g, 0.0051g and 0.0061g, and then add them to the seven small beakers in order, and finally add 10mL ethanol to the ...

[0096] Experimental example 1 Infrared spectrum characterization of samples
[0097] The samples used in this experimental example are prepared from Examples 1-7 and Comparative Example 2.
[0098] Infrared spectroscopy is used to measure that when a sample is irradiated by infrared light with continuously changing frequencies, the molecules absorb radiation of certain frequencies, and the dipole moment changes caused by its vibrational or bending motion, causing the energy level to change from the ground state to the excited state. Transitions to form a molecular absorption spectrum.
[0099] Take a small amount of the above sample powders, add them to potassium bromide powder, grind them until they are evenly mixed, press them into thin slices, and then use Fourier transform infrared spectrometer to perform infrared spectroscopy on the catalyst. figure 1 Shown, where
[0100] Curve a represents ZrO 2 The infrared spectrum;
[0101] Curve b represents the infrared spectrum of the sam...
