Electroreforming of Glucose/Xylose Mixtures On PdAu Based Nanocatalysts

The electroreforming of glucose/xylose mixtures has been evaluated at Pd1-xAux/C anodes in 0.10 mol L−1 NaOH electrolyte. catalysts synthesized by a wet chemistry route are comprehensively characterized physicochemical and electrochemical techniques. From linear scan voltammetry situ Fourier transform infrared spectroscopy measurements, it was shown that the Pd0.3Au0.7/C material led to best electrocatalytic behavior towards electrooxidation terms activity (higher current densities lower potentials) selectivity (lower dissociative adsorption). Six-hour chronoamperometry measurements were performed 293 K 25 cm2 electrolysis cell +0.4 V +0.6 reaction products analyzed high performance liquid chromatography. main gluconate xylonate, but contributions xylose all formed always percentages than initial ratios solutions, showing glucose more electro-reactive Pd0.3Au0.7 surface.
