“…Then the results were as follows. Please notice that in the following chart, the amounts of saturated fatty acids and unsaturated fatty acids in the final produced fuel are mentioned [8]. It is expected that by increasing the density of the catalyst up to a determined level, the quality of the biofuel will be increased.…”

In the past decade, biodiesel has been noticed as a reproducible, non-toxic and lucrative fuel. This fuel is in fact the FATTY ACID METHYL ESTER which has been resulted from Trans-esterification of Tri-glyceride. It´s expected that biodiesel will be developed throughout the world with a greater pace. With regards to the importance of biodiesel production, 18 samples of this biofuel have been made out of sunflower oil in three reaction temperatures of 60, 70, 80, C with two catalysts (potassium hydroxide & sodium hydroxide) with different weights of 0.5, 1, 1.5 % with 300 rpm agitation intensity under Alcohol to water ratio of 1:5 in 60 minutes period. the consequences showed that the high quality of this biofuel resulted from the catalyst of potassium hydroxide with weight percentage of 1 in comparison to the other two weight percentages of 0.5 & 1.5.

“…The growing biodiesel market in Malaysia as Malaysia is the world's largest producer of palm oil will lead to surpass the capacities of glycerol as a by-product. Fuels such as glycerol have drawn an attention because they are renewable from biomass production, less harmful, have high energy density, low vapor pressure, low cost, and easy storage and transportation needs [5][6].…”

In this study, Aurum (Au) was used as the second metal in palladium catalyst (Pd) and carbon nanofiber (CNF) as catalyst support for glycerol oxidation. Second metal and catalyst support will help to improve catalytic activity and decrease adsorbed oxidation intermediates species. Carbon nanofiber supported PdAu nanoparticles was synthesized by using trisodium citrate as stabilizing agent and sodium borohydride as reducing agent. Physicochemical characterizations of the catalyst were performed by X-ray Diffraction (XRD), Transmission Electron Microscope (TEM), Field Emission Scanning Electron Microscope (FESEM) and Brunauer-Emmett-Teller (BET) to study the nature of the catalysts. The electrochemical activity for oxidation of glycerol on PdAu/CNF was evaluated in half cell under alkaline media by cyclic voltammetry potentiostat. The densities and mass activity obtained from half-cell analysis were 73.81 mA cm -2 @ 492.04 mA mg -1 , 63.82 mA cm -2 @ 425.44 mA mg -1 and 55.73 mA cm -2 @ 371.54 mA mg -1 for PdAu/CNF, Pd/CNF and Au/CNF, respectively in 1 M KOH + 0.5 M glycerol electrolyte. The electrochemical study, exhibited the superior performance of bimetallic PdAu/CNF catalyst as compared to monometallic Pd/CNF. This indicate that the electronic coupling between Pd and Au can promote the electrocatalytic activity for glycerol oxidation.Keywords: PdAu, carbon nanofiber, glycerol oxidation, alkaline media Abstrak Dalam kajian ini, Au telah digunakan sebagai logam kedua dalam pemangkin paladium dan gentian nano karbon sebagai sokongan pemangkin kepada pengoksidaan gliserol. Logam kedua dan sokongan pemangkin akan membantu meningkatkan aktiviti pemangkin dan mengurangkan perjerapan spesis pertengahan pengoksidaan. PdAu dengan disokong oleh gentian nano karbon telah disintesis dengan menggunakan trisodium sitrat sebagai ejen penstabil dan natrium borohidrat sebagai agen penurunan. Pencirian fizikal-kimia pemangkin telah dijalankan oleh pembelauan sinar-X (XRD), Mikroskop Elektron Penghantaran (TEM), Mikroskop Imbasan Elektron (FESEM) dan Brunauer-Emmett-Teller (BET) untuk mengkaji sifat pemangkin. Aktiviti elektrokimia untuk pengoksidaan gliserol pada PdAu/CNF dinilai dalam sel separuh di bawah media beralkali dengan menggunakan kitaran voltammetri potentionstat. Ketumpatan arus dan berat aktiviti yang diperolehi daripada analisis sel separuh adalah 73.81 mA cm -2 @ 492.04 mA mg -1 , 63.82 mA cm -2 @ 425.44 mA mg -1 dan 55.73 mA cm -2 @ 371.54 mA mg -1 masingmasing untuk PdAu/CNF, Pd/CNF dan Au/CNF, dalam 1 M KOH + 0.5 m gliserol elektrolit.
