Ketjenblack supported Ni electrocatalysts (Ni/C) with nickel content from 20% to 70% were synthesized by the impregnation method using freeze-drying. Cyclic voltammetry, transmission and scanning electron microscopy were applied for characterization of the Ni electrocatalysts. The prepared samples were tested in the glycerol electrooxidation reaction in alkaline media along with Ni black and Ni rod. It turned out that the onset potentials of glycerol electrooxidation were notably lower for the supported Ni electrocatalysts than for Ni black and Ni rod. Among the supported Ni electrocatalysts, the sample with nickel content of 60% was found to be the most active. The onset potential for glycerol electrooxidation on 60% Ni/C is about 200 mV lower than the values reported in the literature.
