Promotion Mechanisms of Au Supported on TiO2 in Thermal- And Photocatalytic Glycerol Conversion
Abstract
<p>Catalytic glycerol conversion by means of either photon or thermal energy is of great importance and can be realized by metal supported on TiO<sub>2</sub> systems. Although various procedures have been employed to synthesize efficient metal/TiO<sub>2</sub> catalysts, the promotional mechanisms for both reactions are still unclear due to the lack of well-defined systems. Here, we have deposited gold nanoparticles on a series of highly crystalline anatase TiO<sub>2</sub> substrates with different crystallite sizes (7, 12, 16, 28 nm) by both direct precipitation and sol-immobilization methods to examine the effect of metal deposition methods and TiO<sub>2</sub> sizes on both photo- and thermal catalytic glycerol reforming. For photocatalytic H<sub>2</sub> evolution from glycerol, optimum performance was observed for the Au supported on 12 nm TiO<sub>2</sub> for both deposition methods. For thermal catalytic glycerol oxidation, all catalysts show a similar selectivity to glycerate (>70%) regardless of the TiO<sub>2</sub> size and metal deposition method; however, the metal deposition method significantly influences the catalytic activity. In situ UV-vis spectrometry reveals that the optimized photocatalytic performance originates from enhanced charge transfer kinetics and a more negative Fermi level for proton reduction, whereas electrochemical analysis reveals that the promoted glycerol oxidation is caused by the enhanced oxygen reduction half-reaction.</p>
