Polymer-based catalysts have never been used before as anode catalysts in direct formic acid fuel cells. At present, Poly (acrylic acid), Poly (AA) was prepared and electrodes were constructed on graphite pencil (G) from these hydrogels. Furthermore, Pd doped Poly (AA)/G electrodes were prepared by employing electrodeposition techniques, and their formic acid electrooxidation (FAEO) activities were examined via cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy. These electrodes were characterized by DT-TGA, FTIR, and SEM-EDX. It was observed that Poly (AA)/G wer ...More
Herein, carbon nanotube (CNT)-supported Ga@PdAgCo catalysts were synthesized by sodium borohydride (SBH) sequential reduction method. These catalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma-mass spectrometry (ICP-MS). Characterization results revealed that these catalysts were succesfully preared at desired loading and atomic ratios. From the XRD pattern, the crystallite size of 0.5 Ga@PdAgCo(80:10:10)/CNT catalysts was found as 6.95 nm by utilizing the Scherrer equation. From ...More
At present, poly(methacrylic acid) (MA), poly(MA) hydrogel, and Pd-doped poly(MA) hydrogel modified electrodes are constructed on graphite pencil (G). The Pd precursor is coated on the poly(MA)/G electrodes surface using the electrodeposition method. These electrodes are characterized by thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy, and scanning electron microscopy-energy dispersive X-ray. Poly(MA) hydrogel and Pd-doped poly(MA) hydrogel are successfully prepared by the polymerization and further electrodeposition. Formic acid electro-oxidation (FAEO) activities ar ...More
