Abstract:
A porous beta-Ga2O3 photocatalyst has been successfully prepared. The photocatalyst was characterized by XRD, N2 adsorption-desorption, TEM, UV/vis, and FTIR techniques. The photocatalytic activity of the sample was evaluated by the decomposition of benzene in air under UV light illumination and was compared with that of the commercial titania (Degussa P25) and Pt/P25. Results revealed that the synthesized Ga2O3 was porous beta-Ga2O3 and was highly photoactive for mineralizing benzene and its derivatives (e.g., toluene and ethylbenzene) to CO2 under ambient conditions. The photocatalytic conversion of benzene over beta-Ga2O3 was about 1 order of magnitude higher than that over P25, and no obvious deactivation of beta-Ga2O3 was observed during the prolonged operation of 80 h. The high activity and long-term stability of the Ga2O3 have been ascribed to its stronger oxidative capability and higher specific surface area in comparison with P25.
