Low-Temperature Synthesis of Visible Light Driven TiO2 Microcrystal

Abstract

The TiO2microcrystal was prepared under low temperature using tetrabutyl titanate as raw material. The TiO2catalyst was characterized by XRD, SEM, TEM, FITR, and PL. At the same time, the degradation performance of TiO2microcrystal on methyl orange was studied in ordinary sunlight conditions. The experiments show that TiO2microcrystal at 85°C with 50 mL nitric acid as a crystal control agent can be obtained. Meanwhile, the light absorption of catalyst can be extended to the visible light; the methyl orange can be degraded within 100 min under visible radiation.
