氯氧化铋半导的制备及其光催化性能的应用研究

通过调整反应的pH以及给予不同的后处理方式，以水热法合成了不同形貌的氯氧化铋，采用XRD、SEM、紫外可见分光光度计等手段对其组成、形貌和光催化性能进行了表征，考察不同合成条件下的氯氧化铋对罗丹明B和甲醛的降解性能。拓展了氯氧化铋在液相污染体系和气相污染体系中对有机污染物降解的应用。实验表明:BiOCl（9U）和BiOCl（6）均获得了最好的光催化效果，其对罗丹明B的降解率在10 min和20 min时均达到了99%，而氯氧化铋则在120 min时对高质量浓度甲醛的降解率达到67%。

Preparation of bismuth oxychloride crystals and application of its photocatalytic properties

BiOCl with different morphologies was synthesized by the hydrothermal method，along with adjusting the pH of the reaction and different post-processing methods. The structure, morphologies and photocatalytic properties of the synthesized BiOCl were characterized by XRD, SEM, UV-VIS spectrophotometer. BiOCl synthesized under different conditions was researched for its properties of degrading rhodamine B and formaldehyde, thus expanding the application of BiOCl in the degradation of organic pollutants in liquid phase and gas phase pollution systems. Experimental results show that BiOCl（9U）and BiOCl（6）demonstrate optimum photocatalytic effects, with a 99% degradation rate of rhodamine B at the 10^th minute and the 20^th minute. BiOCl’s degradation rate of high concentration formaldehyde reached 67% at the 120^th minute.
