Active and stable Cu doped NiMgAlO catalysts for upgrading ethanol to n-butanol
文献摘要：
Upgrading ethanol to n-butanol is an attractive way for renewable n-butanol production.Herein,Cu was selected to modify NiMgAlO catalysts for improving ethanol conversion and n-butanol selectivity.Over the optimized 2％Cu-NiMgAlO catalyst,ethanol conversion and n-butanol selectivity were enhanced to 30.0％and 64.2％,respectively,in 200 h time on stream at 523 K.According to physicochemical character-izations and theoretical calculations,the key role of multiple active sites in this reaction was extensively investigated.The plate-like structure of hydrotalcite was maintained over 2％Cu-NiMgAlO catalysts,with an average Ni particle size of ca.5.4 nm.The presence of Cu species created CuNi alloy sites and Lewis acid-base pairs,and increased hydrogen transfer and condensation reactions,resulting in elevated etha-nol conversion and n-butanol selectivity.Additionally,CuNi alloy had a strong interaction with CuNiMgAl oxides,forming homogeneous boundary due to their close ionic radius and lattice matching,and afforded the long time stability in the ethanol to n-butanol reaction.
