每周分享：Basicity–FAME yield correlations in metal cation modified MgAl mixed oxides for biodiesel synthesis

   今天给大家分享的是2014年7月份 《Catalysis Communications》上发表的一篇名为：Basicity–FAME yield correlations in metal cation modified MgAl mixed oxides for biodiesel synthesis

文章摘要如下：

In this paper Zn2 +, Co2 +, Fe3 + and La3 + were respectively introduced into Mg3Al1 mixed oxides to prepare Mg1Zn2Al1, Mg1Co2Al1, Mg3Al0.6Fe0.4 and Mg3Al0.6La0.4 oxides by calcinations at 773 K. The XRD, XPS, BET, ICP-AES and CO2-TPD characterizations of samples exhibited that the effects of the substitution of trivalent cations (Fe3 +, La3 +) for Al3 + on the basicity of samples were stronger than the substitution of divalent cations (Zn2 +, Co2 +) for Mg2 + because of high O2 ? concentration which were coincident with the FAME yield for these catalysts. La3 + modified catalyst exhibited highest activity in transesterification.
