摘要：
Potassium salt prepared AMO-MgxAl-LDH(K) (x = 2-5) have been studied as catalyst precursors for biodiesel synthesis. Calcined potassium salt prepared [AMO-Mg0.75Al0.25(OH)(2)](CO3)(0.17)K-0.01 {AMO-Mg3Al-LDH(K)} with high surface area (366.1 m(2) g(-1)) and Lewis basicity density (2.87 mu mol m(-2)) catalyses the transesterification of sunflower oil with methanol to yield fatty acid methyl esters (FAMEs) after 300 minutes (99%), a much higher performance than conventional LDHs.
