Abstract:
Functionalised carbon black (CBsn, Vulcan XC 72-R) and functionalized multi-walled carbon nanotube (MWCNTsn) supported 20%Pd-10%Ni-10%Sn catalyst were successfully synthesised by impregnation-reduction method using sodium borohydride as a reducing agent. Thermal gravimetric analysis (TGA), Raman spectroscopy, and Fourier transform infrared spectroscopy (FTIR) were used to confirm the surface modification for carboxyl functional group. Energy dispersive spectrometry (EDX) was employed to verify the ratio of metal loading and metal dispersion by elemental mapping. Temperature programmed reduction (TPR) and CO-pulse chemisorption technique were used to determine the percentage of metal dispersion and number of active sites of the electrocatalyst. Cyclic voltammetry (CV) and chronoamperometric (CA) were used to investigate the catalyst activity and durability which associated to the alcohol oxidation reduction in 1M KOH and 1M alcohol. Methanol, ethanol, iso-propanol, and glycerol were used as fuel for alcohol oxidation reduction of mono and binary carbon supported catalyst. CBsn and MWCNTsn ratio of 0:100, 25:75, 50:50, 75:25 and 0:100 (w/w) were used as supported material. It was found that the functionalised MWCNT supported 20%Pd 10%Ni-10%Sn catalyst exhibited the highest current density of EOR and superior to others for durability. A performance of the fuel cell using H2 gas as a fuel with Pd based catalyst had lower open circuit potential than Pt-based catalyst for anode.
