• , BiOCl, and (BiO)2CO3, most Bi-based compounds have bandgaps that may be stimulated by visible light. As a result, much interest in environmental cleanup and energy conversion research has been sparked by Bi compounds [24]. Because of their advanced photocatalytic process, more and more publications on

• energies. Many persistent organic contaminants can be degraded at room temperature through the oxidizing power of VB holes in bismuth oxyhalides [26]. BiOCl, BOI, BiOBr, and composites made from them have been widely reported due to their excellent photocatalytic properties [27][28][29]. However, the

• simple hydrothermal synthesis for preparing 2D BiOCl nanosheets [83]. This was accomplished by altering the pH value of the precursor solution and using of dulcitol (C6H14O6) as surfactant. The pH value substantially influenced the thickness of the nanosheets and the fraction of exposed (001) facets. The

A large number of Bi2O3-based heterojunctions, such as Bi2O3/g-C3N4 [46], WO3/g-C3N4/Bi2O3 [47], Bi2O3/BiOCl [48], Bi2O3/ZnO [49], and Bi2O3/BiVO4 [50] have been synthesized. However, to the best of our knowledge, there is no report

• 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 composite. The results show that the catalytic performance of the BTD composite under visible-light irradiation is much higher than that of TiO2 or BiOCl
