Transesterification Of Palm Cooking
Oil Using BiFeO3 Nanocatalyst.
Masters thesis, Universiti Sains Malaysia.
Abstract
A novel heterogeneous bismuth ferrite nanocatalyst was successfully
synthesized via facile biotemplated technique (BiFeO3) using polysaccharides of
kappa-carrageenan with an aim to study its efficiency transesterification reaction of
palm cooking oil. Pure BiFeO3 with particle size of 95.8 nm was obtained using 1:2
molar ratio of Bi to Fe with 1 % carrageenan biotemplate and calcined at 823 K for 2
hours. The produced nanocatalyst possess high thermal stability and X-ray diffraction
(XRD) result confirmed the purity of its rhombohedral crystalline phases.
