摘要：A highly photoactive Ti-containing Cr-modified MCM-48 photocatalyst was prepared by a facile onestep method at room temperature. A combination of various physicochemical techniques such as X-ray diffraction (XRD), diffuse reflectance UV–vis spectra (DRS) and scanning electron microscopy (SEM) were used to characterize the properties of the synthetic catalysts. The characterization and experimental results indicated that tetrahedral Ti oxide moieties as dominant Ti oxide were loaded into the mesoporous structure and there was a synergistic interaction between the Ti species anchored on the walls and the Cr ions presented in the MCM-48 framework, which was considered to be directly correlated to the photoactivity. The optimized for maximum hydrogen production of 333.41 mL was found to be 2 g catalyst dosage, 722 W/m2 light intensity and 60 min of irradiation
