Electrocatalytic Oxidation of Glycerol using Electrolessly Deposited CuNiSnP Electrocatalysts Supported on Carbon in Alkaline Media
The electro-oxidation of glycerol (EOG) has gained wide attention as an alternative to producing value-added chemicals for glycerol valorization. In this study, a multimetallic electrocatalyst containing copper (Cu), nickel (Ni), tin (Sn), and phosphorus (P) was supported on a carbon catalyzed substrate (CCS) using an electroless deposition technique and evaluated for EOG. The effect of the electroless deposition time (15, 30, and 45 min) was also studied. Characterization of the CuNiSnP/CCS electrocatalyst via X-ray diffraction, scanning electron microscopy, and inductively coupled plasma optical emission spectroscopy revealed the formation of a thin-film morphology containing Cu as the main species on the surface and covering the carbon substrate. The electrochemical performance evaluation showed that the electrocatalyst obtained after 30 min of electroless deposition produced the maximum current density (6.5 mA/cm2). The multimetallic composition of CuNiSnP/CCS provided better reaction performance than related tri- (CuNiP/CCS and NiSnP/CCS), bi- (NiP/CCS), and monometallic (Cu/CCS) composites according to the peak current densities for the forward (if) and backward (ib) oxidation, the if/ib ratio, and the onset potential. Furthermore, CuNiSnP/CCS exhibited more stable and stronger resistance to poisoning. Overall, this study demonstrates the potential of the new electrode material CuNiSnP/CCS as an effective electrocatalyst for EOG.
