Pt@TiO2 core–shell nanostructures were prepared through a hydrothermal method. The dye-sensitization of these Pt@TiO2 core–shell structures allows for a high photocatalytic activity for the generation of hydrogen from proton reduction under visible-light irradiation. When the dyes and TiO2 were co-excited through the combination of two irradiation beams with different wavelengths, a synergic effect was observed, which led to a greatly enhanced H2 generation yield. This is attributed to the rational spatial distribution of the three components (dye, TiO2, Pt), and the vectored transport of photogenerated electrons from the dye to the Pt particles via the TiO2 particle bridge.

Monoclinic scheelite BiVO4 was synthesized from a mixture of aqueous Bi(NO3)3 and NH4VO3 solutions by hydrothermal method. Then using successive coating of BiVO4 with a carbon layer and a ZrO2 layer followed by heat treatment to remove the carbon layer prepared a core-shell(ZrO2@void@BiVO4) nanoparticles with a void layer between the BiVO4 core and the ZrO2 shell. TG-DTA and IR suggest that BiVO4 was coated with ZrO2. TEM shows that there was a void space between the BiVO4 core and the ZrO2 shell. The samples were characterized by XRD and the peaks of ZrO2@void@BiVO4 suits well with the pure phase monoclinic scheelite BiVO4. And its visble-light photocatalytic activity was evaluated by the photodegradation of methylene blue(MB). The results indicated that the photocatalytic activity of ZrO2@void@BiVO4 is similar to that of pure phase BiVO4, which makes it can be used for preparing liquid-gas phase boundary visble-light photocatalyst.
