Example Embodiment
[0019] Embodiment 1
[0020] Weigh 3.16 g of sodium bismuthate and disperse it in 40 mL of absolute ethanol. Make up 1.2 molL -1 40 mL of dilute hydrochloric acid, weigh potassium iodide with an equimolar amount of chloride ions in the prepared hydrochloric acid solution and dissolve it in the hydrochloric acid to form a hydrochloric acid-potassium iodide mixed solution, and the mixed solution is added dropwise to 1 mL of sodium bismuthate at a rate of 8 minutes. In anhydrous ethanol suspension, a suspension solution was obtained after stirring for 1.5 h. The suspension solution was suction filtered, and the filter cake was washed three times with distilled water and absolute ethanol, and then dried at 40 °C to obtain a visible light-responsive BiOCl photocatalyst.
[0021] The obtained photocatalyst is used for oxidative treatment of rhodamine B or methylene blue aqueous solution. The degradation steps are:
[0022] Step (1): Accurately weigh 7 mg of Rhodamine B or meth...
Example Embodiment
[0025] Embodiment 2
[0026] Weigh 6.32 g of sodium bismuthate and disperse it in 80 mL of absolute ethanol. Make up 1.2 molL -1 80 mL of dilute hydrochloric acid, weigh potassium iodide with an equimolar amount of chloride ions in the prepared hydrochloric acid solution and dissolve it in the hydrochloric acid to form a hydrochloric acid-potassium iodide mixed solution, and the mixed solution is added dropwise to 1 mL of sodium bismuthate at a rate of 10 minutes. In anhydrous ethanol suspension, a suspension solution was obtained after stirring for 2 h. The suspension solution was suction filtered, and the filter cake was washed three times with distilled water and absolute ethanol, and then dried at 50 °C to obtain a visible light-responsive BiOCl photocatalyst.
[0027] The obtained photocatalyst is used for oxidative treatment of rhodamine B or methylene blue aqueous solution. The degradation steps are:
[0028] Step (1): Accurately weigh 7 mg of Rhodamine B or methy...
Example Embodiment
[0031] Embodiment 3
[0032] Weigh 1.58 g of sodium bismuthate and disperse it in 20 mL of absolute ethanol. Make up 1.2 molL -1 20 mL of dilute hydrochloric acid, weigh potassium iodide with an equimolar amount of chloride ions in the prepared hydrochloric acid solution and dissolve it in the hydrochloric acid to form a hydrochloric acid-potassium iodide mixed solution. In anhydrous ethanol suspension, a suspension solution was obtained after stirring for 1.5 h. The suspension solution was suction filtered, and the filter cake was washed three times with distilled water and absolute ethanol, and then dried at 45° C. to obtain a visible light-responsive BiOCl photocatalyst.
[0033] The obtained photocatalyst is used for oxidative treatment of rhodamine B or methylene blue aqueous solution. The degradation steps are:
[0034] Step (1): Accurately weigh 7 mg of Rhodamine B or methylene blue solid, dissolve it in distilled water, and dilute to 1000 mL to obtain 7 mg·L -1 ...
