The Structure, Morphology and Catalytic Performance of a Silica Supported Cu Catalyst for Ethylene Glycol Synthesis
A silica supported Cu catalyst with good performance for ethylene glycol (EG) production was prepared by the hydrolysis of tetramethoxysilane (TMOS) in one phase solution using methanol as co-solvent, followed by the precipitation of copper on SiO2 by ammonia evaporation. XRD, SEM and TEM were carried out to characterize the structural and morphology properties of the catalyst. The results showed that Cu particles were homogeneously dispersed on the support and thus lead to the high catalytic performance.
