| ¡¡ Preparation of M/Ti-MCM-41 Photocatalyst and
Its Performance of Hydrogen Production 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. ¡¡ |
