The design of MOF-based micromotors (MOFtors) is still challenging and with limited approaches, especially for the MOF nanoparticles (NPs). Herein, we report a universal and straightforward strategy to efficiently self-assembly MOF NPs into robust MOFtors for enhanced organic-or heavy-metalion-contaminants remediation without mechanical stirring. Based on the transient Pickering emulsion method, Fe 3 O 4 @NH 2 -UiO-66 (Fe-UiO) NPs are rapidly selfassembled into Fe 3 O 4 @NH 2 -UiO-66 colloidosomes (Fe-UiOSomes) on a large scale, and the formation mechanism is systematically studied. The Fe-UiOSomes-Pt micromotors through chemical reduction (Micromotor-C) presented a higher motility of 450 � 180 μm s À 1 in a 5 wt% H 2 O 2 aqueous solution. Finally, the bubblepropelled Micromotor-C was employed to efficiently remove dyes and heavy metal ions (94 % for MO and 91 % for Cr VI ).
Three-dimensional motion (especially in the Z-axis direction) of the Metal−Organic Frameworks (MOFs)-based micromotors (MOFtors) is essential but still in its infancy. Herein, we propose a simple strategy for designing light-driven...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
