There is an increasing interest in the application of gallium oxide as a catalyst support material, with particular interest in its use in new methanol steam reforming catalysts. Infrared studies on the interaction of hydrogen on Ga2O3 yield distinct bands attributed to the Ga-H stretch of chemisorbed hydrogen atoms. This proposal of MAPS beamtime seeks to use INS to access the Ga-H bending modes of a hydrogen saturated gallium oxide surface, which will provide information on the number of adsorption sites. Quantification of the INS spectrum will enable the relative partitioning between the different sites to be estimated.
