Abstract:
A two-phased solvothermal method was employed to synthesize BiOCl nanoplates using Bi(NO3)3·5H2O, sodium
oleate and KCl as the starting materials. The phases, morphology and optical property of the products
were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and UV-vis
diffuse reflectance spectroscopy (DRS). XRD and TEM images showed that the BiOCl nanoplates have a tetragonal
phase with the lateral length of 50–100 nm. DRS exhibited that the obtained BiOCl samples have
great absorption in the ultraviolet light range. Methyl orange (MO) and Rhodamine B (RhB) were used as the
target degradation to assess the photocatalytic properties of the samples. Under UV irradiation, the degradation
rate of MO and RhB was reached to 96.3 % and 97.7 % within 30 min. The results indicated that the
BiOCl nanoplates have great potential applications in dye degradation.
