Cu2O decorated carbon-incorporated TiO2 microspheres with enhanced visible light photocatalytic activity
Source abstract
Abstract
Abstract Carbon-incorporated TiO 2 microspheres (CTMs), produced by a flame assisted hydrolysis method, were successfully decorated with Cu 2 O nanoparticles via a chemical bath deposition process. A red shift of absorption edge and enhanced visible light absorption were observed for the resulted Cu 2 O/CTMs composites compared with bare TiO 2 and CTMs. Their effective visible-light-driven photocatalytic activity and the effect of deposition amount of Cu 2 O on the photocatalytic properties were determined by the degradation of methylene blue. The highest degradation rate was achieved for Cu 2 O/CTMs composite (29.2%) compared to CTMs (18.5%) and bare TiO 2 (7.3%) under visible light illumination for 80 min. The improved photoactivity can be ascribed to the integrative synergistic effect of carbon and Cu 2 O on TiO 2 . This work develops a rapid and facile approach for the fabrication of Cu 2 O decorated carbon-incorporated TiO 2 microspheres composites and demonstrates it is an efficient route to improve the photocatalytic activity of TiO 2 .
