  • Organic wastewater treatment method based on multi-element co-doping TiO2 nano photocatalytic material
    Patent number: 11534741
    Abstract: An organic wastewater treatment method based on a multi-element co-doping TiO2 nano photocatalytic material includes preparing a sulfur-titanium dioxide mixture, hydrothermally reacting the sulfur-titanium dioxide mixture with copper chloride, ammonia, strong alkali, a transition metal salt and the like, reacting the resulting reaction product with hydrofluoric acid, then performing temperature programming thermal treatment in air to obtain the multi-element co-doping TiO2 nano photocatalytic material, and then treating organic wastewater with the multi-element co-doping TiO2 nano photocatalytic material under the irradiation of visible light.
    Type: Grant
