Ethanol dehydrogenation by gold catalysts: The effect of the gold particle si…

A range of silica-supported gold nanoparticle catalysts have been synthesized on various silica supports. The particle size was varied between 1.7 and 15 nm by varying the support (ordered mesoporous silicas, silicas with and without aluminium impurities) and the gold loading procedure. A strong influence of the gold particle size on the non-oxidative dehydrogenation of ethanol is noted: gol…
