Silica-Supported MoO3 Catalyst Prepared by Alkoxide Method.

Highly dispersed silica-supported molybdenum catalysts were prepared by an alkoxide method, using ethylsilicate and ammonium paramolybdate dissolved in ethylene glycol. By comparing temperature-programmed sulfiding(TPS) spectra of the catalysts with those of alumina or silica-supported catalysts formed by an impregnation method, the structures and the dispersion states of molybdenum oxide in the catalysts prepared by the alkoxide method were discussed.
