H2 production with low CO selectivity from photocatalytic reforming of glucose on metal/TiO2 catalysts

H-2 with low CO concentration is produced via photocatalytic reforming of glucose (as a representative of biomass component) on metal/TiO2 catalyst (metals: Pt, Rh, Ru, Ir, Au, Ni, Cu). It is shown that the loaded metals generally enhance the rate of H-2 production, while they depress the CO selectivity. Both H-2 production and CO selectivity are strongly dependent on the kind of deposited metals on TiO2. For example, Rh/TiO2 catalyst is found to be most active for H-2 production while with the most extremely low CO concentration from the photocatalytic reforming of glucose.
