Abstract

Engineering metal-oxide interfaces in TiO2/nanoporous (np) Au inverse catalysts results in enhancement of H2oxidation activity. While the intrinsic activity of the novel np-Au prepared from a Au-Si alloy is low, the activity increased as the weight fraction of the TTIP (amount of TiO2) was increased to 0.5 weight%. We correlate the change in activity with the active sites at the perimeter interface between the TiO2and np-Au.
