In this report, we investigated an electrochemical oxidation of formic acid using electrodeposited platinum (Pt) nanostructures on graphene oxide (GO) coated glassy carbon (GC) electrode. The modified electrode is well characterized with the aid of cyclic voltammetry (CV), scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman analyses. A crystalline flower-like Pt nanostructures were found on GO modified electrode. The GO-Pt modified electrode displayed improved catalytic current signal in formic acid oxidation than the bare GC and Pt nanastrutures modified electrodes. The loading of GO amount dependent catalytic performance was studied to optimize the GO amount for the efficient electrocatalytic activity. The mass activity of the GO-Pt modified electrode is 2.2 times higher than the Pt modified electrode in formic acid electrooxidation. The GO-Pt nanostructures show good stability in amperometric i-t curve and consequently, show the higher turnover number than the only Pt modified electrode.

Promotional Effect

The yolk-shell Fe3O4-polyaniline for decoration of Pd-Ni nanoparticles (yolk-shell Fe3O4-PANI/Pd-Ni) were synthesized and used as a new electrocatalyst for oxidation of formic acid. The yolk-shell Fe3O4-PANI/Pd-Ni catalyst provided superior catalyst performance for formic acid oxidation in H2SO4 aqueous solution. These yolk-shell Fe3O4-PANI/Pd-Ni catalysts were found to be more resistant to deactivation in the oxidation of formic acid than yolk-shell Fe3O4-PANI/Pd and Pd/C and to consistently show better long-term performances. The enhanced catalytic performance may arise from the unique structure and surface properties of the yolk-shell Fe3O4-PANI and bi-functional effect, which process extraordinary promotional effect on Pd catalyst.
