Synthesis of a CoTiO3/BiOBr heterojunction composite with enhanced photocatalytic performance
Source abstract
Abstract
Abstract A novel heterojunction CoTiO 3 /BiOBr nanocomposite with enhanced photocatalytic performance was synthesized by a precipitation-deposition method. The samples were characterized by transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and UV–vis spectrophotometry. Moreover, the photocatalytic activities were evaluated by decomposing the dye molecule Rhodamine B under visible light irradiation. The results showed that high photocatalytic performance can be achieved on the heterojunction photocatalysts, with the 0.15CoTiO 3 /0.85BiOBr composite displaying the highest activity. The results of the study concluded that it was the introduction of CoTiO 3 into the catalyst that mainly enhanced the activity of the photocatalyst by promoting the separation of the electron-hole group on the interface between BiOBr and CoTiO 3 .
