The preparation, characterization, and electrooxidation of colloidal palladium modified poly(methacrylic acid) hydrogel as formic acid fuel cell anode catalyst

Nahit AKTAŞ

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 ...Более
