RESUMO:

In this work has been presented the process of remediation of pollutants in aqueous medium using PEDOT/Pt, ZrO₂-GO/Pt micromotors and Janus micromotors of magnesium in the treatment of CO₂ capture, removal of nerve agents used in chemical bombs and in the removal of nitrite, respectively. Environmental sustainability has been one of the greatest challenges today. Concerns about the excessive uses of natural resources and a minimization of the impact caused in the environment have led to great advances in the field of nanotechnology. Recent studies on the use of micromotors have shown that the combination of the constituent components of these micromachines and their propulsion has shown a high efficiency in the removal of pollutants in the environment. All micromotors presented excellent results such as the capture of 90% carbon dioxide promoted by the PEDOT/Pt micromotors, 91% removal of methyl paraoxon using the hybrid ZrO₂-GO/Pt micromotors and 92.8% removal of the nitrite using the Janus micromotors of magnesium.
