摘要

Spheroidal and dodecahedron metal-organic frameworks (MOFs)-based catalytic micromotors were synthesized by one-step method through changing the solvent. The morphology and composition of the final products were characterized by scanning electronic microscope, Fourier-transform infrared spectra, transmission electron microscope and X-ray diffraction. The dodecahedron micromotors exhibit eximious performance that they can move autonomously in 10% hydrogen peroxide with a speed of 61.39 mu m s(-1). Moreover, the micromotors show a long movement life of 90 min. Owing to the special character of MOFs, the micromotors can dramatically adsorb the organic pollutants within 5 min. The spheroidal micromotor shows better adsorption efficiency for its higher surface area, which benefits from its hollow structure.
