Summary: | The invention discloses a rectorite/cuprous oxide/titanium dioxide composite photocatalyst which is a product prepared with the following steps: rectorite is added into a copper sulfate solution, and the mixture is well mixed by stirring; an ascorbic acid solution is added, and the mixture is well mixed; titanium dioxide is added, and the mixture is stirred; a sodium hydroxide solution is added under ultrasonic agitation; and ultrasonic treatment, centrifugation, water washing, alcohol washing, bake drying, and grinding are carried out, such that the rectorite/cuprous oxide/titanium dioxide composite photocatalyst is obtained. The preparation process is simple; the raw material prices are low; and the raw materials are environment-friendly. The prepared rectorite/cuprous oxide/titanium dioxide composite photocatalyst has a high-efficiency algae-killing rate and degradation rates of water body pollutants such as humic acid and phosphorus-containing substances. The photocatalyst is applicable to the fields such as water treatment and hydration process. |
