Abstract
The mesoporous CdS/TiO2 composites were synthesized by a sol–gel method combined with solvothermal method. The material showed the gel block-like structures which were composed of heterogeneous spherical gel particles, the average size of the particles was about 14[Formula: see text]nm, with specific surface area as 300.254[Formula: see text]m2[Formula: see text]g[Formula: see text]. The mesoporous CdS/TiO2 composites exhibited a wide absorption band to simulated sunlight whose adsorb wavelength reached to 550[Formula: see text]nm, its absorption intensity and catalytic performance of photocatalytic water-producing hydrogenation were also increased with the increase of CdS contents. When the molar ratio of TiO2:CdS was 1:1, the photocatalytic activity reached the highest, and the average hydrogen production rate reached 2167.32[Formula: see text][Formula: see text]mol[Formula: see text]g[Formula: see text][Formula: see text]h[Formula: see text].
