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 μm 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.

用于染料吸附的形状控制的催化ZIF-67微电机
通过改变溶剂,通过一步法合成了基于球形和十二面体的金属有机骨架(MOF)。通过扫描电子显微镜,傅立叶变换红外光谱,透射电子显微镜和X射线衍射来表征最终产物的形态和组成。十二面体微电机表现出卓越的性能,它们可以在10%的过氧化氢中以61.39μms -1的速度自主移动。此外,微电机的运动寿命长达90分钟。由于MOF的特殊特性,微型电机可以在5分钟内显着吸收有机污染物。球形微电机由于其较高的表面积而表现出更好的吸附效率,这得益于其空心结构。
