Publikováno v: ChemPhysChem

Catalytic properties of In-Pt intermetallic compounds in methanol steam reforming have been investigated. In2Pt has been proven to be mandatory for a high activity and selectivity. Only small amounts of In2O3 have been found to be beneficial for cata

Ultrathin layers of oxides deposited on atomically flat metal surfaces have been shown to significantly influence the electronic structure of the underlying metal, which in turn alters the catalytic performance. Upscaling of the specifically designed
