BiOCl/TiO₂/diatomite composites with enhanced visible-light photocatalytic activity for the degradation of rhodamine B.

ABSTRACT: A BiOCl/TiO₂/diatomite (BTD) composite was synthesized via a modified sol-gel method and precipitation/calcination method for application as a photocatalyst and shows promise for degradation of organic pollutants in wastewater upon visible-light irradiation. In the composite, diatomite was used as a carrier to support a layer of titanium dioxide (TiO₂) nanoparticles and bismuth oxychloride (BiOCl) nanosheets. The results show that TiO₂ nanoparticles and BiOCl nanosheets uniformly cover the surface of diatomite and bring TiO₂ and BiOCl into close proximity. Rhodamine B was used as the target degradation product and visible light (λ > 400 nm) was used as the light source for the evaluation of the photocatalytic properties of the prepared BTD compos
