Low-Temperature Synthesis of Visible Light Driven TiO₂ Microcrystal

Abstract:

The TiO₂ microcrystal was prepared under low temperature using tetrabutyl titanate as raw material. The TiO₂ catalyst was characterized by XRD, SEM, TEM, FITR, and PL. At the same time, the degradation performance of TiO₂ microcrystal on methyl orange was studied in ordinary sunlight conditions. The experiments show that TiO₂ microcrystal 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.
