Preparation of Cu-Ni/C Catalyst at Low Temperature for Synthesis of Dimethyl Carbonate (DMC)[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2011,50(6):78-81.DOI:
Carbon supported copper-nickel alloy catalysts (Cu-Ni/C) were prepared by the low temperature hydrothermal reduction method. The Cu-Ni/C catalysts were characterized by FTIR
XRD,SEM and TEM analyses. The results indicated that the graphite oxide (GO) and metal precursors could be reduced at the same time. The TEM images showed that the alloy particles were well dispersed at the carrier surface with the size less than 50 nm for the catalyst synthesized at 90 ℃. The catalysis performances for direct syntheses of DMC form CO

and CH

OH were investigated and the highest CH

OH conversion of 4.2% and the DMC selectivity of 84.5% could be achieved.
