英文摘要: The reaction and adsorption of syngas and paraformaldehyde on Ru-Co/SiO2 ca-talysts prepared from Ru-Co bimetallic carbonyl clusters have been investigated by infrared, mass spectroscopies. The spectra of reaction of CO+H-2 with Ru-Co/SiO2 catalysts showed a band appearing at 1584 cm(-1), which has a good relationship to the activity and selectivity for oxygenates in CO hydrogenation. Thus it was proposed that 1584 cm(-1) is a possible intermediate to produce oxygenated products. Isotopic tracer studies of D-2 and (CO)-C-13 suggest that 1584 cm(-1) can possibly be assigned to the formyl group, which is in good agreement with the adsorption of paraformaldehyde. The chemical trapping of 1584 cm(-1) adspecies provided an evidence to demonstrate that 1584 cm(-1) is attributed to formyl. The reaction of 1584 cm(-1) species with H-2 produced CH4 and CH3OH, and the introduction of D-2 into 1584 cm(-1) species resulted in the formation of CHD3 and CHD2OD.
