Synthetic nano-and micromachines hold immense promise in biomedicine and environmental science. Currently, bubbledriven tubular micro/nanomotors have garnered increasing attention owing to their exceptional high-speed self-propulsions. However, complex and low-yield preparation methods have hindered their widespread applications. Herein, we present a generalized, scalable, and low-cost electrospinning-based strategy to fabricate MnO 2 -based composite tubular micromotors (MnO 2 -TMs) for efficient heavy metal ion removal. The inherent flexibility of precursor nanofibers derived from diverse matrix materials enables the creation of MnO 2 -TMs with a wide range of morphologies. In response to morphology changes, the MnO 2 -TMs, based on a bubble-propelled mechanism, exhibit multimodal motion patterns, including linear, circular, and spiral to stochastic swinging. To elucidate the underlying morphologyto-motion relationship, we conducted systematic simulations of fluid dynamics around the MnO 2 -TMs. Furthermore, by incorporation of Fe 3 O 4 nanoparticles, the capabilities of MnO 2 -TMs can be expanded to include magnetic manipulation for directional navigation and efficient retrieval. Benefiting from these attributes, MnO 2 -TMs excel in removing heavy metal ions from water. The developed MnO 2 −MnWO 4 @Fe 3 O 4 TMs exhibit prominent adsorption capacities of 586.5 mg g −1 for Cu 2+ and 156.4 mg g −1 for Pb 2+ . Notably, the magnetic property facilitates rapid separation and retrieval of the micromotors, and the absorbed ions can be simply recovered by pH adjustment. This work establishes a general framework for developing MnO 2 -based tubular micro/nanomotors to address environmental challenges.
