General description

Electrochemical oxidation of 2,3-dihydroxybenzaldehyde in methanol at various pH has been studied using cyclic voltammetry and controlled-potential coulometry.

Application

2,3-Dihydroxybenzaldehyde was used in the synthesis of copper(II) complexes of Schiff bases[1]. It was also used in the synthesis of 2-ethoxy-3-hydroxy-4-nitrobenzoic acid[2].

In the present work, a graphene encapsulated ZnO/Co3O4 (GE/ZnO/Co3O4) core-shell hybrid is fabricated through a facile self-assembly approach, where the mutual electrostatic interaction force drives the ZnO/Co3O4 heteronanostructures to be fully wrapped with flexible ultrathin graphene shells. The as-prepared GE/ZnO/Co3O4
