INS examination of potential hydrogen spillover on pure and metal decorated metal oxides

Abstract: Metal oxides(MO) are widely used in technological applications especially for catalysts and supports for catalysts. We propose to use the inelastic response of H2 adsorbed on well-characterized Au decorated ZnO and (Pd, Au) decorated alumina nanoparticles to probe the molecule metal and molecule MO interactions. We chose these materials because they are have been used as hydrogenation catalysts. Hydrogen spillover is believed to be an important mechanism for hydrogenation catalysis. This proposal represents the next phase of our study of the surface mediated chemical reactivity of pure and doped MO nanomaterials and builds on our previously published work on MgO and ZnO. We will combine Z contrast <1Å resolution STEM, state of the art ab initio DFT, thermodynamics and reaction kinetics with these INS studies to extend the current microscopic knowledge of hydrogen spillover.
