摘要：

A novel photocatalyst In(OH)(3) was synthesized by peptization of a colloidal precipitate under ultrasound radiation. The photocatalyst was characterized by N-2 adsorption, XPS, XRD, UV-vis DRS, and FTIR technologies. The photocatalyst sample is highly photoactive and stable for gas-phase removal of benzene under UV irradiation, even in dry O-2 atmosphere. Both the conversion of benzene and the mineralization yield are notably accelerated, as compared to the widely used photocatalyst - titania (Degussa P25). ln(OH)(3) is active even after 30 h of photoreaction. The maximal conversion and mineralization ratio of benzene achieved are 33.4% and 56%, respectively, which is much higher than that obtained with TiO2 (9.5% and 24%). The high activity and durability of the ln(OH)(3) can be ascribed to the high hole oxidation potential and carbon deposits formed uneasily on the catalyst surface.
