Photochemical Hydrogen Production from a Water-Methanol Mixture with Iron Oxide Suspensions
Kim, I.K.,Salmeron, M.,Hendewerk, M.,Somorjai, G.A. 圓光大學校 基礎自然科學硏究所 1986 基礎科學硏究誌 Vol.5 No.2
Photochemical hydrogen production has been detected from small particles of doped iron oxide suspended in a methanol-water(1:1) mixture. The systems studied consisted of a pure n-type semiconductor, Fe_(2-x)Nb_XO_3 (x=0.02); a pure p-type semiconductor, La_(1-X)Sr_XFeO_3 (x=0.25), and Mg-doped α-Fe_2O_3. The efficiency of the reaction increased substantially when the powders were loaded with Pt. Of the systems investigated Mg-doped α-Fe_2O_3 showed the highest efficiency. In the case of Mg-doped α-Fe_2O-3 the existence of spinel phase inclusions in the α-Fe_2O_3 corundum structure remarkably enhances the photocatalytic reactivity, which may be a result of a cathodic shift of the conduction band edge of the corundum structure and also an increase in the conductivity of the material material. Hydrogen production from these Mg-doped iron oxides is photocatalytic and occurs mainly as a result of bandgap irradiation, but also occurs with sub-bandgap illumination. There is a linearly increasing dependence of the H_2 production with increasing light intensity.
