ABSTRACT The rational design of noble metal‐free electrocatalysts represents one the basic stones for fuel cell development. With exploration eco‐friendly nanomaterials investigated alcohol oxidation process, nickel‐based electrodes have been recognized as most auspicious anodes with promoted activity and stability. In this work, a series NiCo 2 O 4 nanoparticles were deposited onto graphite sheets (NiCo /T) introducing varied proportions cobalt oxide species. Co‐precipitation protocol respective metallic hydroxides carbonaceous support was followed consecutive annealing in an air atmosphere at 400°C. fabricated mixed nanopowder physically studied using X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), energy dispersive analysis (EDX), photoelectron spectroscopy (XPS), selected area (SAED). Uniformly arranged observed on surface evidenced by SEM TEM. cubic lattice structure formed crystals also confirmed XRD through defined peaks binary oxides clarifying their successful preparation scheme. electrocatalytic properties these /T nanocatalysts evaluated oxidizing ethanol molecules solution. Pronounced current densities remarkably measured relation to that NiO/T. Differing introduced content into synthesized nanocatalyst significantly controlled its catalytic performance. /T‐20 exhibited highest stability among prepared nanomaterials. Much decreased charge transfer resistances recorded electrode demonstrating characteristics. This work could provide reasonable route simple synthesis comparable transition promising attitudes generation purposes.
