Hydrogen peroxide (H2O2) is an oxidizing agent commonly used for various applications and is available in aqueous solution in a wide range of concentrations. This work describes the H2O2 electrogeneration process in alkaline medium (KOH 1.0 mol L−1), using an unmodified gas diffusion electrode (GDE)...
