Au/TiO 2 , Au 0.75 Cu 0.25 /TiO 2 , Au 0.5 Cu 0.5 /TiO 2 and Au 0.25 Cu 0.75 /TiO 2 photocatalysts prepared from pre-formed Au and Au–Cu alloy nanoparticles of controlled composition and size were loaded over ceramic honeycombs (2 mg cm −2 ) and tested in an optical...
In the study described in this paper we deposited gold, silver and copper on γ-Al2O3 as nanoparticles (<4 nm) and investigated the behavior of these nanoparticles in the preferential oxidation of CO in presence of H2. In addition, the effect of addition of CeOx and/or Li2O was investigated. All the three metals show preferential oxidation of CO at low temperatures. The oxides added to Au/γ-Al...
