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.
