  text: In the quest for alternate and efficient electrode materials, ternary metal
    electrocatalysts (TMEs), part of the perovskite family, were synthesized and tested
    for methanol electro-oxidation in alkaline media. La0.5Ca0.5MO3 (M = Ni, Co, or
    Mn) was synthesized via sol-gel method. X-ray diffraction analysis revealed that
    the perovskite crystal structure possesses characteristic sharp and crystalline
    peaks for all synthesized ternary electrocatalysts. The average particle size
    calculated using Debye–Scherrer equation was in the order of La0.5Ca0.5NiO3 (LCNO)
    > La0.5Ca0.5CoO3 (LCCO)> La0.5Ca0.5MnO3 (LCMO). The elemental composition of as
    prepared sample, LCCO was investigated via x-ray fluorescence spectroscopy. The
    qualitative and quantitative analysis revealed the presence of La, Ca and Co in
    parent crystal structure with percentage compositions of 9.0, 3.12 and 87.82%
    respectively. The particle size distribution was homogenous, as determined by
    scanning electron and transmission electron microscopes. The electrocatalytic
    activity of the synthesized ternary electrocatalysts was studied electrochemically
    by cyclic voltammetry. The calculated diffusion coefficient values showed that
    electrode surface of LCNO and LCCO have limited efficiency for diffusion related
    phenomenon. The heterogeneous rate constants inferred better electrode kinetics
    of LCCO and LCNO which exhibited good electrocatalytic behavior; sharp anodic
    peaks were observed in the potential range of +0.3 to 0.6 V and +0.6 to 0.8 V,
    respectively. Methanol electro-oxidation was found minimal in case of LCMO sample.
    We have observed that Co substitution at B-site of perovskite electrode materials
    attains better electrochemical properties, thus in relation with reported literature.
