RT Journal Article T1 Reusable and Long‐Lasting Active Microcleaners for Heterogeneous Water Remediation A1 Parmar, Jemish A1 Vilela García, Diana A1 Pellicer, Eva A1 Esqué‐de los Ojos, Daniel A1 Sort, Jordi A1 Sánchez, Samuel AB Self‐powered micromachines are promising tools for future environmental remediation technology. Waste‐water treatment and water reuse is an essential part of environmental sustainability. Herein, we present reusable Fe/Pt multi‐functional active microcleaners that are capable of degrading organic pollutants (malachite green and 4‐nitrophenol) by generated hydroxyl radicals via a Fenton‐like reaction. Various different properties of microcleaners, such as the effect of their size, short‐term storage, long‐term storage, reusability, continuous swimming capability, surface composition, and mechanical properties, are studied. It is found that these microcleaners can continuously swim for more than 24 hours and can be stored more than 5 weeks during multiple cleaning cycles. The produced microcleaners can also be reused, which reduces the cost of the process. During the reuse cycles the outer iron surface of the Fe/Pt microcleaners generates the in‐situ, heterogeneous Fenton catalyst and releases a low concentration of iron into the treated water, while the mechanical properties also appear to be improved due to both its surface composition and structural changes. The microcleaners are characterized by scanning electron microscopy (SEM), X‐ray photoelectron spectroscopy (XPS), nanoindentation, and finite‐element modeling (FEM).
