| 英文摘要 | time-resolved ir spectroscopy was used to detect the photocatalytic reaction of methanol for h-2 production on pt/tio2 catalysts. there exists an optimal amount of pt loading in the pt/tio2 catalysts for the reaction of the photogenerated long-lived electrons. for a given amount of pt loading, the reaction rate of the long-lived electrons on pt/tio2 catalysts varies greatly with the different reduction temperature of the catalysts. the possible reason is that the pt particles occupy the surface active sites for methanol adsorption on pt/tio2 catalysts reduced at high temperature. this phenomenon is not observed obviously on pt/tio2 catalysts reduced at low temperature. the decay rate of the long-lived electrons evaluated by time-resolved ir method qualitatively correlates well with the activity of h-2 production under steady-state irradiation conditions. |
