NOVELTY - The method for producing a non-enzymatic glucose electrochemical sensor involves (A) adding copper(II) acetate to aqueous graphene oxide solution, mixing, dripping aqueous ammonia, stirring to obtain brown solution, transferring the brown solution to a high temperature and high pressure reaction kettle, reacting, washing resulting black deposits with water, centrifuging and then drying, and (B) mixing the copper oxide nanoneedle/nitrogen-doped graphene nanocomposite material, graphite powder and paraffin oil to form uniform carbon paste, and filling the carbon paste into a glass tube. USE - Method is useful for producing a non-enzymatic glucose electrochemical sensor (claimed). ADVANTAGE - The method ensures the production of the non-enzymatic glucose electrochemical sensor with high detection efficiency in a simple manner. DETAILED DESCRIPTION - The method for producing a non-enzymatic glucose electrochemical sensor involves (A) adding 100-300 mg copper(II) acetate to 3-5 ml of 1 mg/ml aqueous graphene oxide solution, ultrasonically mixing for 30-60 minutes, dripping 5-8 ml of 28 mass% aqueous ammonia, stirring for 20-30 minutes to obtain brown solution, transferring the brown solution to a high temperature and high pressure reaction kettle, reacting at 150-200 degrees C for 15-24 hours, washing resulting black deposits with water, centrifuging and then drying at 60 degrees C to obtain copper oxide nanoneedle/nitrogen-doped graphene nanocomposite material, and (B) mixing the copper oxide nanoneedle/nitrogen-doped graphene nanocomposite material, graphite powder and paraffin oil in a ratio of 0.5:2:0.8 for 1 hour to form uniform carbon paste, filling the carbon paste into a glass tube having an inner diameter of 3 mm and a length of 5 cm, inserting a copper wire from the end to an electrode connector to obtain the non-enzymatic glucose electrochemical sensor.
