Abstract

Zr-MCM-41 was prepared via incorporation of Zr into the amorphous wall of MCM-41 in the hydrothermal synthesis process. Experimentally, photocatalytic generation of hydrogen on Zr-MCM-41 was investigated in a total reflectance system. In the presence of Zr-MCM-41, hydrogen yield (22.4 μmol H₂/h) in the photocatalytic decomposition of H₂O was highly enhanced by at least 2.5 times over that of the conventional photocatalyst ZrO₂. The enhancement may be due to the high dispersion of ZrO₂ and the justified band gap between the conduction band and valance band of ZrO₂ in the wall of MCM-41. This work demonstrates how photodecomposition of H₂O was affected by high dispersion of photoactive species (ZrO₂) in the amorphous wall of MCM-41.
