NOVELTY - A mixture of graphene and magnesium chloride is dissolved in isopropanol, and ultrasonic is performed for 2 hours, to obtain uniform suspension liquid. The obtained suspension solution is heated to 70-80 degrees C, stirred and refluxed. Potassium permanganate is dissolved in deionized water. The obtained potassium permanganate solution is added to obtained suspension solution, stirred, refluxed for 2 hours, cooled to room temperature, filtered, washed and vacuum dried at 50 degrees C, to obtain manganese oxide-loaded graphene catalyst used for preparing amide by oxidizing alcohol ammonia. USE - Manganese oxide-loaded graphene catalyst is used for preparing amide by oxidizing alcohol ammonia. ADVANTAGE - The manganese oxide-loaded graphene catalyst has favorable activity with respect to ammoxidation of aromatic alcohol, unsaturated alcohol, fatty alcohol and other organic substances, can be recycled by simple process. DETAILED DESCRIPTION - A mixture of graphene and magnesium chloride is dissolved in isopropanol, and ultrasonic is performed for 2 hours, to obtain uniform suspension liquid. The obtained suspension solution is heated at 70-80 degrees C, stirred and refluxed. Potassium permanganate is dissolved in deionized water. The obtained potassium permanganate solution is added to obtained suspension solution, stirred, refluxed for 2 hours, cooled to room temperature, filtered, washed and vacuum dried at 50 degrees C, to obtain manganese oxide-loaded graphene catalyst used for preparing amide by oxidizing alcohol ammonia. The mass ratio of magnesium chloride and graphene is 2:1-8:1. The mass ratio of isopropanol and graphene is 100:1-900:1. The mass ratio of potassium permanganate and graphene is 1:1-5:1. The mass ratio of water and graphene is 50:1-300:1.
