主　　题：Dimethyl maleate Tetrahydrofuran Copper phyllosilicate Silica supported copper Copper valence state 

摘      要：Cu/SiO2 catalysts prepared by different methods have been investigated focusing on the influence of Cu^＋on the catalytic *** composition,structure and copper valence state were characterized by means of BET,XRD,XPS,FTIR,*** was found that the Cu/SiO2 prepared by ammoniaevaporation（AE） method had much higher TOF value than that prepared by wetness-impregnation（WI）with the same THF *** higher TOF value was attributed to the coexistence of Cu^＋ and Cu^0species in the activated AE-Cu/*** only Cu° species existing in the activated Wl-Cu/*** suggest that Cu^＋ can adsorb and polarize the C=0 bond of *** is concluded that Cu°could be the main active site and the synergistic effect between Cu^0 and Cu^＋ could contribute to hydrogenation of DMM to THF.
