A series of photocatalytically composite materials, CdS/Al-HMS and Pt/CdS/Al-HMS, were prepared by templete reagent, ion exchange, precipitation and impregnation methods. The photocatalysts were characterized by using X-ray diffraction (XRD), transmission electron microscope (TEM), X-ray fluorescence analysis (XRF), UV-Visible diffuse reflectance spectrum
technology. The results show that the structure of the composite material CdS/Al-HMS mainly depends on the amount of CdS in Al-HMS. The doping composite material is formed with low content of CdS and the nanoscale composite material is produced with high content of CdS. The photocatalytic activities of hydrogen productions for coupled materials are carried out by photocatalytic formic acid degradation under visible light irradiation (λ≥420nm). The result indicates that the composite material loaded 6% Pt shows the highest hydrogen generation rate of 22.3mL/h with an apparent quantum yield of 12% at the wavelength of 420nm.
