Abstract: A method of fabricating a magnetically-controlled graphene-based micro-/nano-motor includes: (a) mixing FeCl3 crystal powder with deionized water to obtain a FeCl3 solution; (b) completely immersing a carbon-based microsphere in the FeCl3 solution; transferring the carbon-based microsphere from the FeCl3 solution followed by heating to allow crystallization of FeCl3 on the surface of the carbon-based microsphere to obtain a FeCl3-carbon-based microsphere; (c) heating the FeCl3-carbon-based microsphere in a vacuum chamber until there is no moisture in the vacuum chamber; continuously removing gas in the vacuum chamber and introducing oxygen; and treating the FeCl3-carbon-based microsphere with a laser in an oxygen-enriched environment to obtain the magnetically controlled graphene-based micro-/nano-motor. A magnetically-controlled graphene-based micro-/nano-motor is further provided.
