Embodiment approach 1
[0018] Weigh 0.05 mol of potassium chloride and 0.05 mol of potassium dihydrogen phosphate respectively, dissolve them in 100 mL of distilled water, and prepare an electrolyte solution. After polishing the metal bismuth plate and titanium plate, they were cleaned and dried with ethanol and deionized water successively; the bismuth plate was used as the anode and the titanium plate was used as the cathode, which were placed in the electrolyte solution and reacted for 7 hours under the condition of 2V voltage and magnetic stirring. After the reaction, BiPO is obtained at the anode 4 / BiOCl composite catalyst film, washed three times with absolute ethanol and deionized water, and then dried in an oven at 40 ° C, that is, BiPO was obtained at the anode 4 / BiOCl composite catalyst film.
[0019] The obtained photocatalyst is used for oxidation treatment of phenol solution. The reaction conditions are: under normal temperature and pressure, 50mL of 10mg / L phenol solution, using th...
Embodiment approach 2
[0021] Weigh 0.05 mol of potassium chloride and 0.05 mol of potassium dihydrogen phosphate respectively, dissolve them in 100 mL of distilled water, and prepare an electrolyte solution. After polishing the metal bismuth plate and titanium plate, they were cleaned and dried with ethanol and deionized water successively; the bismuth plate was used as the anode and the titanium plate was used as the cathode, which were placed in the electrolyte solution and reacted for 5 hours under the condition of 5V voltage and magnetic stirring. After the reaction, BiPO is obtained at the anode 4 / BiOCl composite catalyst film, washed three times with absolute ethanol and distilled water, and then dried in an oven at 40 ° C, that is, BiPO was obtained at the anode 4 / BiOCl composite catalyst film.
[0022] The obtained photocatalyst is used for oxidation treatment of phenol solution. The reaction conditions are: under normal temperature and pressure, 50mL of 10mg / L phenol solution, using th...
Embodiment approach 3
[0024] Weigh 0.05 mol of potassium chloride and 0.05 mol of potassium dihydrogen phosphate respectively, dissolve them in 100 mL of distilled water, and prepare an electrolyte solution. After the metal bismuth plate and titanium plate were polished, they were cleaned and dried with ethanol and deionized water successively; the bismuth plate was used as the anode and the titanium plate was used as the cathode, which were placed in the electrolyte solution and reacted for 4 hours under the condition of 7V voltage and magnetic stirring. After the reaction, BiPO is obtained at the anode 4 / BiOCl composite catalyst film, washed three times with absolute ethanol and distilled water, and then dried in an oven at 40 ° C, that is, BiPO was obtained at the anode 4 / BiOCl composite catalyst film.
[0025] The obtained photocatalyst is used for oxidation treatment of phenol solution. The reaction conditions are: under normal temperature and pressure, 50mL of 10mg / L phenol solution, usin...
