this research, Palladium nanoparticles were decorated on the MWCNT via chemical rote by sodium borohydride as a reducing agent; obtained nanocatalyst was coated on the carbon ceramic electrode and used as an electrocatalyst for oxidation of formic acid. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses were performed for characterize the nanostructure of the MWCNT-supported Pd catalyst. The fabricated electrode (Pd/MWCNT/CCE) was used as an anode for the electrooxidation of formic acid (FA) in 0.1 M H2SO4 solution. It was found that Pd/MWCNT/CCE was catalytically more active than Pd nanoparticles (alone) supported on the same substrate. On the other hand, the results showed that the presence of MWCNT greatly enhances the activity of Pd towards the electrooxidation of FA. Moreover, the Pd/MWCNT/CCE catalyst has satisfactory stability and reproducibility for electrooxidation...
