Over the years, many metallic, bimetallic and metal on oxide catalysts have been developed and investigated for biomass processing. Most studies are focused on metals rather than the combination of both metals and oxide supports. In this presentation, Pt, one of the most active metal catalysts in H2 production from biomass, is dosed on different transition metal oxides including SiO2, TiO2, CeO2 and ZrO2. To find out the interaction between Pt and oxides, the catalysts are characterized with Brunauer-Emmett-Teller (BET), chemisorption, temperature programmed desorption (TPD), temperature programmed reduction (TPR), and synchrotron-based X-ray diffraction and X-ray absorption(XAS). The interactions and activities of the samples are tested with ethanol, ethylene glycol and glycerol reactants. Part of the results will be presented.
