The invention discloses a method for preparing a γ-Fe 2 O 3 /MnO 2 magnetically permeable bubble-driven micromotor by using poplar fiber as a template, which uses poplar fiber as a template and simultaneously loads γ-Fe 2 O 3 and MnO 2 , a γ-Fe 2 O 3 /MnO 2 magnetically permeable bubble-driven micromotor was prepared, which can reach inaccessible polluted areas through magnetic guidance and bubble drive for cleaning treatment, and can be recycled through an external magnetic field after treatment to avoid It causes secondary pollution; the present invention uses poplar fiber as a template, which is a kind of plant-derived pollution, is not valued by people, is easy to obtain, and has low cost, and the prepared micromotor has excellent adsorption performance and recycling performance, and is environmentally friendly. The field has potential application value. |
