Description

Technical field [0001] The invention belongs to the technical field of nano material preparation and application, and relates to a preparation method of an antibacterial silver molybdate graphite phase carbon nitride composite visible light catalyst. Background technique [0002] In recent years, with the development of industry, energy problems and environmental pollution problems have become more and more serious. The photocatalytic technology based on solar energy for photocatalytic degradation of pollutants has also attracted more and more attention from scientists. The development of new photocatalysts and the adjustment of the original photocatalyst structure to increase its photocatalytic activity have become popular research directions. In addition, the treatment of bacteria in sewage is another important research in sewage treatment, but there is little research on the combination of photocatalytic treatment of water pollutants and water disinfection and sterilization. ...
