Electrochemical fabrication of nanoporous gold electrodes in a deep eutectic solvent for electrochemical detections

Abstract

Deep eutectic solvents are a class of green and sustainable solvents in chemical processes. An electrochemical method was developed to fabricate nanoporous gold electrodes by alloying and dealloying Au–Zn alloy in ZnCl₂–urea deep eutectic solvent. The as-prepared active nanoporous gold electrodes facilitate the electrochemical detections of water pollutants with superior sensitivities.
