[0030] A rod-shaped Cu x The preparation method of O photocatalytic material, comprises the following steps:
[0031] (1) Add anhydrous copper sulfate, cetyltrimethylammonium bromide and water into a beaker, stir well to obtain a mixed solution; the concentration of anhydrous copper sulfate in the mixed solution is 0.01 ~ 2.00 mol / L, cetyl The concentration of alkyltrimethylammonium bromide is 0.001 ~ 0.1 mol / L;
[0032] (2) Add the egg film into the above beaker, stir evenly to obtain a suspension, the concentration of the egg film in the suspension is 0.1-10mg / mL;
[0033] Wherein, the treatment method of the egg membrane is as follows: take out the egg white and egg yolk from the egg to obtain the eggshell, remove the egg membrane in the eggshell by physical stripping, wash the egg membrane with deionized water, dry it, and cut it into a size of 1 ~ 1.2 cm × 1 ~ 1.2 cm;
[0034] (3) Transfer the suspension above to the eggshell, then place the eggshell in a beaker filled...
