介绍了双金属掺杂介孔分子筛Ti-Ce-MCM-41的合成及结构表征,并用来催化降解内分泌干扰化学物壬基酚.该催化剂以十六烷基三甲基溴化铵为模板剂,钛酸四丁酯为钛源,采用水热方法合成.在光降解实验中,讨论了溶液的初始浓度、催化剂投加量、pH值以及光照时间对去除率的影响.结果表明:在催化剂投加量为4 mg/L,光照时间为90 min,pH值为5时,可以达到最佳去除效果.

Mesoporous silica molecular sieve Ti-Ce-MCM-41 was successfully prepared via hydrothermal synthesis,by using cetyltrimethylammonium bromide (CTAB) surfactants as template and tetrabutyl titanate as titanium source. The synthesized bimetallic photocatalyst was characterized and subsequently employed to evaluate the removal of an endocrine disrupting chemical (EDC),namely nonylphenol (NP). Several parameters,such as initial concentrations of NP,initial pH value,amount of catalyst and reaction time,were systematically investigated. The experimental outcome demonstrated when initial pH value,amount of catalyst and reaction time were fixed as 5,4mg/L,and 90min,respectively.
