蒸氨法制备铜硅催化剂的二甲醚水蒸气重整制氢性能
Catalytic Performance for Hydrogen Production through Steam Reforming of Dimethyl Ether over Silica Supported Copper Catalysts Synthesized by Ammonia Evaporation Method
摘要
Abstract
A series of xCu/SiO2-AE catalysts with different Cu Ioadings was prepared by the ammonia evaporation method.The as-prepared catalysts were used for hydrogen production via steam reforming of dimethyl ether,and showed high catalytic activities.The 30Cu/SiO2-AE catalyst (with 30％ (w) Cu loading) exhibits the best catalytic performance.Our studies reveal the presence of highly dispersed CuO and copper phyllosilicate on the surface of the catalysts,which can then be reduced to Cu0 and Cu+ species,respectively.Compared with the 30Cu/SiO2-IM catalyst prepared by the conventional impregnation method,the remarkable catalytic stability and activity of the 30Cu/SiO2-AE catalyst are mainly ascribed to its unique lamellar structure and the cooperative effect between the surface Cu0 and Cu+ species.关键词
