Schematic process for the degradation of polluted water (rhodamine 6G as model contaminant) into inorganic products by multifunctional micromotors. The self-propulsion is achieved by the catalytic inner layer (Pt), which provides the motion of the micromotors in H₂O₂ solutions. The remediation of polluted water is achieved by the combination of Fe²⁺ ions with peroxide, generating HO• radicals, which degrade organic pollutants.
