成果简介	NOVELTY - Molybdenum based electrode comprises Graphene oxide coated Nickel Foam or Nickel Graphene electrode. The coat comprises suspension of graphene oxide with water, in the concentration of 15 mg/ml. The electrodes comprises uniform in-situ growth of molybdenum catalyst by respective counter element precursor over the Nickel Foam or Nickel Graphene electrodes. USE - Molybdenum based electrode for electrochemical splitting of sea water. ADVANTAGE - The molybdenum based durable electro catalyst and fabricated electrodes enables sustainable and efficient sea water splitting. The method is low cost, sustainable and easy fabrication of electrodes, provides in-situ formation of Mo-based compounds (B/S/Se/O/P) using a single source precursor is the non-obvious or inventive step and significant changes in the electrochemical properties and stability are observed owing to the presence of counter precursors in the nano system generated. This is critically acclaimed in points of improving/upgrading fabrication strategy, provides ease in fabrication. The precursor is safe, environmental friendly and economic and uniquely all having bifunctional activity, can be used as electrode material for hydrogen and oxygen evolution reaction. The phosphorous form of Mo catalyst exhibited excellent durability in all the pH condition, but over potentials issue found associated with them. All catalyst exhibited bi-functional activity, and provides durability/physical integrity/activity get improved/increased on incorporating graphene oxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for developing the molybdenum-based electrode, which involves: (a) deposition of graphene oxide over Nickel foam or Nickel Graphene electrode through soaking process, and soaking for 2 hours, (b) adding molybdic acid as core precursor into a hydrothermal bomb/ closed reactor comprises 10/60 ml methanol/water and supporting counter precursor in an amount of 1/3rd of the concentration of the molybdic acid. The hydrothermal bomb is further kept inside the muffle furnace operated at 180℃ for 24 hours.
