Summary:An efficient electrocatalyst, based on a nanocomposite involving nickel hydroxide, carbon nitride, and reduced graphene oxide, is synthesized through a facile one‐step electrochemical process for the oxygen reduction reaction in alkaline media. As this novel nanocomposite is comprised of low‐cost, earth‐abundant materials, the good catalytic activity, high stability, and methanol tolerance make this non‐precious‐metal‐based catalyst promising for practical applications. Further reductions: Reduced graphene oxide/carbon nitride supported nickel hydroxide is prepared through an in situ electrochemical process. The fabricated nanocomposite shows great catalytic activity towards the oxygen reduction reaction (ORR) as well as high durability and methanol tolerance. The facile production and cost‐effective precursors accompanied with remarkable performance makes it a promising ORR catalyst.
