| 英文摘要 | silica supported sb-v mixed oxide catalysts (vsbo(x)/sio(2)) were prepared and evaluated in methanol selective oxidation. one-pass yield of formaldehyde at 91% was obtained on one vsbo(x)/sio(2) catalyst. the active phase of vsbo(x)/sio(2) catalysts is found to be sb-v mixed oxide, in which isolated vo(x) species can be stabilized. the relative amount of monomeric vo(x) species in vsbo(x)/sio(2) catalyst is higher than pure supported vo(x) catalyst. on vsbo(x)/sio(2) catalyst, the deep oxidation of intermediates is greatly depressed because the formation of adsorbed acyl species, which leads to co(x). is not favored. the average oxidation state of the vanadium in vsbo(x)/sio(2) catalysts increases with decreasing sb/v ratio. higher oxidation state of the vanadium in vsbo(x)/sio(2) catalysts is found to be relevant to higher activity while v(4+) species are more selective to formaldehyde, sb-v mixed oxide catalyst provides a possibility to adjust the production distribution in methanol selective oxidation by changing sb/v ratio.
