The nanostructured cobalt diselenide (CoSe2) was systematically synthesized onto several chemically modified surface carbon supports. The crystalline structure, morphology and size of synthesized CoSe2 were similar. Oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER) activities were sensitive to the nature of carbon support in acid and alkaline solutions. Both reaction processes were enhanced by the presence of graphitic domains. The electrocatalytic enhancement using chemically modified carbon as a support for cobalt diselenide is discussed.
