Catalysis by Supported Metal Crystallites from Carbonyl Clusters. II. Catalytic Ethanol Synthesis from CO and H2 under Atmospheric Pressure over Supported Rhodium Crystallites Prepared from Rh Carbonyl Clusters Deposited on TiO2, ZrO2, and La2O3

摘要: Ethanol was catalytically produced in the CO–H2 reaction under atmospheric pressure and at 150–250 °C over rhodium crystallite catalysts prepared from Rh carbonyl cluster compounds highly dispersed on La2O3, TiO2, ZrO2. The activity selectivity of ethanol formation depend kind metal oxide used as inorganic carriers. by pyrolysis smaller clusters such Rh2(C5H5)2(CO)3, Rh4(CO)12, Rh6(CO)16 ZrO2 show higher oxygenated products containing (main), acetaldehyde, methanol. contents increased considerably above 200 catalysts. CeO2 ThO2 were also employed preparation pyrolysed to disperse clusters, which catalyses pressure.
