Initial hydrogen emission rate vs. the initial glycerol concentration.This figure represents that the rate of the photocatalytic hydrogen productionquite high. However, the production of hydrogen using Pt/TiO 2 catalysts has a bigdisadvantage: titania based catalysts absorbs UV-light only. In order to shift the bandgap of titania we doped titania by Zn x Cd 1-x S solid solutions. The combination of thesemetal sulfides nanoparticles is easy to synthesize and exhibit absorption andemission properties in a wide wavelength region that allows one to vary the band gapvalue. Platinum was deposited on the surface of these materials as a co-catalyst forthe hydrogen production. These catalysts were characterized by XRD, XPS and UVvisspectroscopy techniques. The adsorption edge of these materials varies from 400to 520 nm that corresponds to the visible-light energy. Preliminary experiments onthe photocatalytic hydrogen production under visible light irradiation were carried out.References[1]. V.M. Daskalaki, D.I.
