| 摘 要： | 以正硅酸四乙酯为硅源，钛酸四丁酯为钛源，溴代十六烷基吡啶为模板剂，合成了具有中孔结构的Ti—MCM-41，并对其进行了第4周期过渡金属氧化物的负载．紫外可见漫反射光谱(UV-Vis)表明，负载金属氧化物后得到的M／Ti—MCM-41的吸收光谱较Ti—MCM-41发生了明显的红移．产氢实验结果表明，在300W高压汞灯照射下，M／Ti—MCM-41的产氢活性较Ti—MCM-41有明显的提高，前者的产氢速率最高可达后者的5．78倍．

| Abstract: | Ti-MCM-41 zeolite with mesoporous structure was prepared taking silica acid tetraethyl ester (TEOS) as Si source, tetrabutyl orthotitante (TBOT) as Ti source, and hexadecylpyridinium bromide (CPBr) as template agent, then loaded with transition metal oxide at row four in the periodic table of elements to result in M/Ti-MCM-41.The ultraviolet-visible diffuse reflectance spectra and experimental results show that the absorption of M/Ti-MCM-41 is red shifted compared with Ti-MCM-41,the performance of hydrogen production is better than that of Ti-MCM-41 under irradiation of 300 W high-pressure mercury lamp, and the highest hydrogen production rate of the former catalyst is as 5.78 times as the latter one. |
