Considering the ever-increasing demand of energy coupled with environmental concerns, alternative energy production/conversion/storage systems, especially full cell, metal air batteries, and electrochemical hydrogen production are highly desirable. Oxygen reduction/ evolution reaction (ORR/OER) and hydrogen evolution (HER) are the key reactions of abovementioned energy harvesting systems. Advanced electrocatalyst based on graphitic carbon nitride (g-C3N4) is designed and fabricated through three key strategies: Firstly, nanosized 1D g-C3N4 nanostructure is designed, prepared, characterized and tested through the facial and large-scale method with high surface area and suitable nitrogen amount. Secondly, Ni/ Co oxides/hydroxides decorated 1D g-C3N4 nanostructures fabricated with controlled Ni/Co+2/+3 as different oxidation states of metals that play important role in electrocatalytic reactions. Thirdly, very thin g-C3N4 nanosheets is coated on 1D nanostructures of metal oxides/hydroxides for M-N(nitrogen) bonding and strong coupling. Finally, these metals along with nitrogen have the intrinsic electrocatalytic activity, so the catalyst designed in such a way to take the advantages of all the active sites and due to pinning of metal oxides/hydroxides on g-C3N4 backbone the well stable and long run electrocatalyst is devolved.
