NOVELTY - Preparation of composite material of 1 T phase molybdenum disulfide.reduced graphene oxide (MoS2.rGO) grown on carbon fiber, comprises (1) placing polyacrylonitrile (PAN), zinc acetate and N,N-dimethyl formamide (DMF) solution in packaging bottle, stirring until the solution becomes clear and transparent adhesive liquid, electrostatic spinning, obtaining precursor of carbon fiber, and drying; (2) annealing the dried carbon fiber precursor, tableting into wafer, soaking in hydrochloric acid, transferring the fiber wafer to deionized water to soak, and drying; (3) dispersing or dissolving molybdenum source, sulfur source and reducing agent in water, adding oxide suspension, stirring, and adjusting pH value to 1-3; transferring to hydrothermal kettle; then placing the carbon fiber wafer in it and completely soaking; and (4) hydrothermally sealing, taking out the carbon fiber wafer, washing with deionized water, and drying at room temperature. USE - Preparation method of composite material of 1 T phase MoS2.rGO for anode material of aqueous zinc ion battery (claimed). ADVANTAGE - The method enables to prepare composite material of 1 T phase MoS2.rGO, which has fast electrochemical performance degradation speed, and high conductivity and hydrophilicity. The method is simple, cost-effective and mild, and has good operation safety. The carbon fiber prepared by the method uniformly vertically grows the composite material with 1 T phase MoS2.rGO grown on the carbon fiber. The product obtained in this process can effectively avoid the defect that the active material of the electrode material is easy to fall off during the washing and drying process and the battery circulation process as the positive electrode of the aqueous zinc ion battery. The material structure is stable, and the conductivity is better than 2 H-phase MoS2. DETAILED DESCRIPTION - Preparation of composite material of 1 T phase MoS2.rGO grown on carbon fiber, comprises (1) placing polyacrylonitrile (PAN), zinc acetate and N,N-dimethyl formamide (DMF) solution at mass ratio of 1: 1: 10 to 1: 1: 12 in 30 ml packaging bottle, stirring at room temperature for 10-12 hours until the solution becomes clear and transparent adhesive liquid, electrostatic spinning at 15 kV, obtaining precursor of carbon fiber, and drying for further use; (2) annealing the dried carbon fiber precursor at 800-900degrees Celsius, tableting the obtained carbon fiber into wafer with diameter of 10-12 mm, soaking in 2-3 mol/L hydrochloric acid for 6-8 hours, transferring the fiber wafer to deionized water to soak for 10-12 hours, and drying at 60-80degrees Celsius for further use; (3) dispersing or dissolving molybdenum source, sulfur source and reducing agent at mass ratio of 1: (1.17-1.25): (10-11.70) in 29.25-28.5 ml water, then adding 0.75-1.5 ml oxide suspension, stirring for 3 hours at normal temperature, adjusting the pH value to 1-3; transferring to hydrothermal kettle; then placing the carbon fiber wafer in it and completely soaking; and (4) hydrothermally sealing at 180-200degrees Celsius for 10-12 hours, taking out the carbon fiber wafer, washing with deionized water, and drying at room temperature. An INDEPENDENT CLAIM is included for the use of composite material of 1 T phase MoS2.rGO.
