摘要
研究了甲烷在负载金属催化剂和离子液体组成的催化系统中氧化为甲醇的反应,考察了不同阴离子的离子液体,负载不同金属催化剂(Au/SiO2,Au-Cu/SiO2,Ag/SiO2,Ag-Cu/SiO2)以及金的不同载体(Au/SiO2,Au/Al2O3)对甲烷转化的作用。实验表明:负载催化剂Au/SiO2催化效果最好,Ag/SiO2,Au-Cu/SiO2,Ag-Cu/SiO2催化效果依次递减,阴离子是Cl-的离子液体对金的促进作用最显著。
The oxidation of methane to methanol in the catalytic systems based on supported metal catalysts and ionic liquids was studied. The effects of different anions of ionic liquids, different SiO2supported metal catalysts （Au/SiO2, Au-Cu/SiO2, Ag/SiO2 Ag-Cu/ SiO2, and different types of supports of gold catalysts （SiO2, Al2O3） on the conversion of methane were investigated. The results showed： （1） among the supported catalysts, Au/SiO2 had the best catalytic performance, while that of Ag/SiO2, Au-Cu/SiO2, Ag-Cu/SiO2 decreased progressively; （2） among the ionic liquids, that with CI＂ as anion showed the best promotion on gold catalysts for the reaction.
