摘要
目的:制备氮掺杂TiO2光催化剂,并对催化剂性能分析.方法:制备氮掺杂TiO2光催化剂,并对其进行比表面积、紫外-可见吸收光谱、光催化活性等测试.结果:随着煅烧温度的不断增加,催化剂比表面积呈现出逐渐递减的趋势;催化剂在400～500 nm波段可见光区域内具有光催化活性;随着煅烧温度的逐步提升,催化剂降解能力逐渐增强,直至400℃时达到最佳状态.结论:氮掺杂TiO2光催化剂在400℃温度煅烧下的各项性能最佳,因此在实际应用中,应将这一温度作为最佳煅烧条件.
Abstract
Objective:To prepare nitrogen doped TiO2 photocatalyst and analyze the performance of the catalyst.Methods:The nitrogen-doped TiO2 photocatalyst was prepared,and its specific surface area,UV-VIS absorption spectrum and photocatalytic activity were tested.Results:With the increase of calcination temperature,the specific surface area of catalyst decreased gradually.The catalyst has photocatalytic activity in the visible region of 400-500 nm band.With the gradual increase of calcination temperature,the degradation ability of the catalyst was gradually enhanced until it reached the best state at 400℃.Conclusion:Nitrogen doped TiO2 photocatalyst has the best calcination performance at 400℃,so this temperature should be used as the best calcination condition in practical application.
