TiO2 is one of the most widely studied metal oxides and attracted significant attention Following. TiO2 nanoparticles have been proposed for a wide range of uses including solar energy conversion, hydrogen storage, improved catalysis, and environmental pollution remediation. TiO2 nanoparticles have been studied for their high photocatalitic activity, high dielectric, and semi-conducting properties, good biocompatibility, but also due to their potential as catalyst or active supports. These properties are different relative to the TiO2 phases and are closely related to its crystal structure, which makes phase transformation one of the most important issues in practical application of the compound. Amorphous TiO2 is of interest for photocatalysis because of its high surface area and high adsorption. Moreover, simple synthesis with elimination of the calcination step would mean lower costs for chemicals and energy consumption. In this study, Amorphous and crystalline TiO2 nanoparticles were probe reaction for comparing adsorption and photocatalytic effect. The TiO2 nanoparticles were characterized using XRD, SEM and FT-IR. |
