A novel autonomous micromotor, based on catalytically pneumatic behaviour of balloon-like MnOx–graphene crumples, has been synthesized via an ultrasonic spray pyrolysis method. Through catalytic decomposition of H2O2 into O2, the gas accumulated in a confined space and was released to generate a strong force to push the micromotor.
