In this paper, a carbon cloth/amorphous nanoscale Pd (CC/AN Pd) composite electrode is reported, which achieves a modifier-free composite of low-cost intractable carbon support and low-loading Pd metal by a mild and facile oxidation-ion exchange-reduction (OIR) route. Compared with the traditional Pd/C electrode, this CC/AN Pd composite electrode exhibits high activity, robustness, cost-effectiveness, modifier-free nature, micro-nano porous structure, and low Pd loading. It shows superior catalysis performance for oxalic acid (OA) oxidization reaction (OOR), especially at high current density. Moreover, based on catalysis performance and the cost of Pd loading amount, this CC/AN Pd composite electrode demonstrates superior catalysis performance for hydrogen evolution reaction (HER) with high cost-effectiveness.
In this paper, we report a carbon cloth/amorphous nanoscale Pd (CC/AN Pd) composite electrode and realizes the modifier-free composite of low-cost intractable carbon support and low-loading Pd metal by designing a mild and facile oxidation-ion exchange-reduction (OIR) route. This CC/AN Pd composite electrode presents high activity, robust, costeffective, modifier-free, micro-nano porous and low Pd loading characteristics compared with the traditional Pd/C electrode. This composite electrode shows superior oxalic acid (OA) oxidization reaction (OOR) catalysis performance, outperforming all the as-reported OOR catalysts especially at high current density. Moreover, on the basis of catalysis performance and the cost of Pd loading amount, this CC/AN Pd composite electrode shows superior hydrogen evolution reaction (HER) catalysis performance with high cost-effective
