Abstract

TiP2O7 carbon composite photocatalyst was successfully prepared by using ion-exchanged resin (C467) containing amino phosphate by metal ion-exchanged carbothermal reduction (MIER-CTR) method using TiCl3 and TiCl4. During the carbonization process in nitrogen, the pre-oxidation (300-350°C) in air is essential for producing homogeneously dispersed TiP2O7 on the carbon matrix. In the absence of pre-oxidation, the resin was melted. The carbonization temperature 500°C was found to be suitable for producing single phase TiP2O7 with higher yields. Powder X-ray diffraction (XRD) and Raman spectroscopic results suggest the formation of TiP2O 7, while X-ray diffraction results reveal that the crystallite size was less than 35nm. UV-Vis studies show that the band gap of TiP 2O7 was 3.32eV. The TiP2O7 carbon composite catalyst was applied for the photocatalytic decomposition of 2-propanol at 30°C using a mercury lamp (365nm).
