▎ 摘　　要

NOVELTY - Preparing graphene/manganese dioxide micro-nano motor comprises (1) taking the template for pretreatment, using a plasma cleaner to bombard the surface for 30 minutes to remove organic impurities on the surface, and thermally evaporating a conductive layer on one side of the template, (2) preparing a graphene deposition solution and a manganese dioxide deposition solution, and adjusting the pH of the manganese dioxide deposition solution, (3) placing the template in an electroplating tank, sequentially using a graphene deposition solution and a manganese dioxide deposition solution for electrodeposition on the template, and performing post-processing to remove the template and obtaining the graphene/manganese dioxide micro-nano motor. USE - The method is useful for preparing graphene/manganese dioxide micro-nano motor, which is useful in waste water treatment (claimed) for degrading methylene blue. ADVANTAGE - The method: is simple. The micro-nano motor: has strong catalytic capability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a graphene/manganese dioxide micro-nano motor; and a method of using graphene/manganese dioxide micro-nano motor in waste water treatment comprising (a) preparing methylene blue solution, (b) preparing mixed solution of hydrogen peroxide and (Nonionic surfactant), (c) taking the mixing solution of the graphene/manganese dioxide micro nano motor and methylene blue solution, hydrogen peroxide and Triton X-100 (Nonionic surfactant) to degrade, (d) using ultraviolet visible spectrophotometer to measure the light transmittance, calculating the degradation rate of the methylene blue.Triton X-100
