Synthesis of paper-based porous gold electrode for electrocatalytic oxidation of ethanol

Herein, to apply porous gold electrode for the electrooxidation of ethanol, we proposed a simple and facile method for the synthesis of paper-based porous gold (PAu) with large surface area using gold nanoparticles (AuNPs) and filter paper. The results showed that Pd/PAu exhibited a large electrochemical surface because of pore size of 100 nm and high electrochemical reaction compared to smooth Au foil and PAu. The as-prepared Pd/PAu electrode exhibited high activity and stability for ethanol electrooxidation in alkaline solution and was reusable even after 100 cycles.
