Biodiesel synthesis from oleic acid by nano-catalyst (ZrO2/Al2O3) under high voltage conditions

Abstract

This paper describes the synthesis and catalytic activity of ZrO₂/Al₂O₃ nano-catalyst as a highly effective heterogeneous and active catalyst that converts oleic acid and methanol into fatty acid esters under high voltage conditions in a low temperature and atmospheric pressure process. Using an inexpensive and reusable catalyst, producing excellent yields in a short time and its environmental benignity are some of the important features of this protocol. The results were confirmed by GC, FTIR, FESEM and XRD.
