Cu AND Cu-BASED AMORPHOUS ALLOY ELECTRODES FOR ANODIC FORMALDEHYDE ELECTRO-OXIDATION

Abstract

Abstract The electrodes of Cu and Cu-based amorphous alloys, a-Cu35Ti65 and a-Cu33Zr67, were very active for the HCHO electro-oxidation in alkaline solutions. The oxidation started at electrode potentials as low as 0.1 V (RHE) and the HF-treated amorphous alloys exhibited high current densities around 40 mA cm−2 (app.) at 0.2 V.
