Abstract & Overview
With butyl titanate as the titanium source, stronger ammonia water as the nitrogen source, glacial acetic acid as the catalyst, and absolute ethyl alcohol as the solvent, this research prepares pure titanium dioxide (TiO2) and nitrogen-doped TiO2 samples by sol-gel method. Furthermore, taking the degradation rate of methyl orange dye as the evaluation index, this research examines the influence exerted by nitrogen-doped TiO2 samples on the degradation performance of methyl orange dye. Concurrently, such methods as X-ray diffractometer and ultraviolet-visible spectrophotometer are employed to characterize the samples. In this foundation, this research investigates the effects of diverse annealing temperatures on nitrogen-doped TiO2 samples. Findings from catalytic degradation experiments reveal that nitrogen-doped TiO2 samples annealed at 400 ℃ exhibit excellent photocatalytic performance.
