Plasma Modified Graphene Oxide Based Ultrafast Micromotors

  

 Self-propelled artificial micromotors based on the catalyt­ic conversion of chemical energy into motion and forces have been of growing interest due to their broad range of (bio) chemical science and industrial applications [1, 2]. Specifically regarding has been given to chemically powered micromotors that display self-propulsion in the presence of hydrogen peroxide (H2O2) fuel [3]. The fuel is very important for self-propelled catalytic micromotor applications [4]. H2O2 fuel where the surface of the platinum based micromotors catalyzes its decomposition to generate water (H2O) and oxygen (O2) bubbles. The motion of chemically propelled micromotors depends on the surfactant and fuel concentration. Fuel concentra­tion affects the rate of bubble generation. Surfactants can increase the interactions between the surface of platinum and H2O2 fuel with decreasing surface tension [5, 6]. Tubular micromotors generally electrochemically synthe­sized because sophistication of template electrosynthesis methods allows new compositions and structures, with improved catalytic performance and new functionalities for micromotors [7]. In this work, GO was produced us­ing hummers method.
