N2 - TiO2 nanospheres with high specific surface area and good crystallinity were prepared by a hydrothermal method using urea as the capping agent and isopropanol as the solvent. The capping agent effectively controlled the morphology of TiO2 nanospheres and led to
improved crystallinity. Using a solvent with a long carbon chain, such as isopropanol, also promoted the formation of TiO2 nanospheres. TiO2 nanospheres with different morphologies were prepared by adjusting the amount of urea. It was found that when TiO2-0.6
was used as the photocatalyst, highest rates of degradation of both methylene blue and rhodamine B under ultraviolet-visible light were observed. Moreover TiO2-0.6 also had the largest hydrogen production efficiency among the different TiO2 samples tested. Thus, TiO2
nanospheres have great development potential and application prospects in environmental management and new modes of energy utilization.
