摘要：
A facile cuprous oxide nanoparticles functionalized electro-reduced graphene oxide modified glassy carbon electrode (denoted as Cu 2 O NPs-ERGO/GCE) was fabricated via a simple physical adsorption and electrochemical reduction approach. Cyclic voltammetry and second-order derivative linear scan voltammetry were used to investigate the electrocatalysis oxidation of vanillin on the Cu 2 O NPs-ERGO/GCE. The compound yielded a well-defined voltammetric response in 0.1 M H 2 SO 4 at 0.916 V (vs. saturated calomel electrode (SCE)). A linear calibrati...
