Synthesis and characterization of NiCr$_{2}$O$_{3}$- CeO$_{2NRs}$ anode electrocatalyst for ethanol electrooxidation reaction in alkaline media

Abstract

In this paper, ceria (CeO2) nanorod (NR) supported Ni-Cr2O3 anode electrocatalysts were synthesized as nonnoble metal -based anode electrocatalysts for ethanol electrooxidation reaction (EOR) in alkaline media. Physicochemical characterization of the electrocatalysts was investigated by XRD, SEM, and TEM techniques. Electrochemical performances of the catalysts were investigated via cyclic voltammetry (CV), linear sweep voltammetry (LSV), and chronoamperometry (CA) techniques. The data from linear LSV were used for the diffusion coefficient of the electrocatalysts. The CA experiments' results showed the tolerance for catalytic poisoning and durability of the synthesized electrocatalysts.
