Effects of Calcination Temperature on Photoreduction Activity of Cu/TiO₂ Nanoparticles

Abstract:

A one step sol-gel method was used for preparation of Cu doped titania nanoparticles (NPs). The crystal structures, morphologies and chemical properties were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). We discussed the calcination temperature effection on the photoreduction activity of Cu/TiO₂. When the calcination temperature was 500°C, the synthesized Cu/TiO₂ performed the highest photocatalytic activity.
