Herein, we report fabrication of MoSe2 functionalized with bimetal Co/Ni particles, which shows promising electrochemical performance in oxygen and hydrogen evolution reactions (OER and HER) due to its physicochemical properties such as electronic configuration and great electrochemical stability. We propose functionalization with two transition metals, cobalt and nickel, expecting a synergic effect in electrocatalytic activity in a water splitting reaction. These electrocatalytic reactions are essential for efficient electrochemical energy storage. The thin flakes were obtained by exfoliation of bulk molybdenum diselenide. Next, after deposition of metals, precursors were carbonized. Electrochemical data reveal that the presence of Ni and Co particles boosts electrocatalyst performance, providing a great number of active sites due to their conductivity. Interestingly, the material exhibited great evolution potential and good stability in long-term tests.
