Anti-corrosion porous RuO₂/NbC anodes for the electrochemical oxidation of phenol.

ABSTRACT: Efficient anode materials with porous structures have drawn increasing attention due to their high specific surface area, which can compensate for the slow reaction rate of electrochemical oxidation. However, the use of these materials is often limited due to their poor corrosion resistance. Herein, we report a facile scale-up method, by carbothermal reduction, for the preparation of porous niobium carbide to be used as an anode for the electrochemical oxidation of phenol in water. No niobium ions were detected when the anodes were under aggressive attack by sulfuric acid and under electrochemical corrosion tests with a current density less than 20.98 mA cm^-2. The porous niobium carbide was further modified by applying a ruthenium oxide coating to improve its catalytic activity.
