Remarkable Improvement of Catalytic Performance for a New Cobalt-Decorated Cu/ HMS Catalyst in the Hydrogenation of Dimethyloxalate...

摘要

Chao Wen and others at the Department of Chemistry and Shanghai Key Laboratory of Molecular Catalysis and Innovative Materials, Fudan University, Shanghai (PRC) fabricated a cobalt-decorated Cu/ hexagonal mesoporous silica (HMS) catalyst with only 1 wt.% cobalt loading and observed a remarkable enhancement in its catalytic performance of converting dimethyloxalate (DMO) to ethylene glycol (EG). The catalyst that was synthesized by a Co-Cu co-ammonia-evaporation method afforded 100% yield of EG, even at a relatively high liquid hourly space velocity (LHSV). After 150 h of time on stream, with a LHSV of 1.2 h~(-1) both the conversion and the selectivity remained unchanged.
