DETAILED DESCRIPTION - Synthesizing manganese molybdate nano-wire/graphene composite material involves using graphene, analytically pure white powder of ammonium molybdate and manganese nitrate as the reaction raw materials, and distilled water as the solvent and dispersant, controllable synthesizing manganese molybdate nanowires/graphene three-dimensional nanocomposites with regular structure and single phase by microwave radiation, accurately weighing 0.0010-10.0000g graphene powder material. The graphene powder has a specific surface area of 750 m2/g, which provides material guarantee for improving the comprehensive performance of the material, placing the weighed graphene powder in 25-250 mL quartz round bottom flask, adding 10-100 mL of distilled water, stirring for 3-5 minutes until the material is uniform to form a black mixed suspension with uniform solid content dispersion. The quartz round bottom flask is placed in an atmospheric microwave reactor with reflux cooling device. The microwave reactor is an improved Midea microwave oven. The microwave reactor power is 200-1400W, the model is PJ21C-AU, and the frequency is 2450 MHz, heated the reaction raw materials to 70-100 degrees C and continue the reaction for 1-10 hours to obtain a uniform black graphene slurry, which is naturally cooled to room temperature for later use, weighed out 5.000-15.0000g analytically pure ammonium molybdate white powder, added to the black graphene uniform slurry obtained by the pretreatment, and stirred for 0.5-3.0 hours to obtain a uniform suspension, measured 5-30 mL 50 wt.% manganese nitrate aqueous solution, the molecular weight of the manganese nitrate is 178.95, and the density is 1.5126g/mL, added 10-150 mL distilled water under strong stirring at 120 rpm, and continue stirred for 0.5-1.5 hours to obtain a homogeneous solution, added the homogeneous solution obtained to the quartz round bottom flask containing the suspension obtained, then placed in the atmospheric microwave reactor with reflux cooling device. The power is set to 200-1400 W, the heating temperature is 70-100 degrees C, and the reaction lasts for 1-10 hours. The product obtained is naturally cooled to room temperature, placed in a high-speed centrifuge at 5000-10000 rpm, and the centrifugation time is set to 1-10 minutes. The obtained precipitate is washed with distilled water for 3-5 times. The product is placed in a blast drying oven at 50-80 degrees C and dried for 5-20 hours to obtain the target manganese molybdate nanowire/graphene powder. The XRD, SEM, and TEM analysis results of the sample confirmed that is a pure phase manganese molybdate nanowire/graphene composite material.
