【摘要】 本研究采用一步溶剂热法合成具有高可见光响应活性的氯氧化铋,并探究溶剂热时间、温度、pH以及氯源对所合成的氯氧化铋光催化活性的影响。实验结果表明溶剂热时间、温度和氯源对氯氧化铋的晶型没有决定性作用,pH对氯氧化铋的晶型有显著的影响。当溶剂热的pH值较低时,能够合成具有(001)晶面择优取向的氯氧化铋,这个条件下合成的氯氧化铋表现出最佳的光催化活性,能够在10分钟内将5 mg/L的罗丹明B溶液降解完毕。更多还原

【Abstract】 The bismuth oxychloride(BiOCl) samples were synthesized by a one-pot solvothermal method. The effect of reaction temperature, time, pH and chloride sources was investigated to reveal the relationship between the photocatalytic properties and the structure and morphology of BiOCl. The result shows that solvothermal temperature, time and chloride sources can’t influence the crystal type of BiOCl, while pH can greatly influence the crystal type of BiOCl. When the solvothermal pH value is lower, it can be more(001) plane exposed BiOCl. And this kind of BiOCl show most excellent photodegradation activity, under visible light irradiation for only 10 min, the photocatalytic performance was up to 99.9%.更多还原
