A sustentabilidade ambiental tem sido um dos maiores desafios na atualidade. Preocupa??es quanto ao uso excessivo de recursos naturais e uma minimiza??o do impacto causado no meio t?m levado a grandes avan?os na ?rea da nanotecnologia. Os recentes estudos quanto ao uso dos micromotores tem mostrado que a combina??o dos componentes constituintes dessas microm?quinas e sua propuls?o t?m apresentado uma alta efici?ncia na remo??o de poluentes no meio ambiente. Todos os micromotores apresentados obtiveram excelentes resultados como a captura de 90% de g?s carb?nico promovido pelos micromotores de PEDOT/Pt, 91% de remo??o de metil-paraoxon usando os micromotores h?bridos de ZrO2-GO/Pt e 92,8% de remo??o do nitrito utilizando os micromotores Janus de magn?sio. / 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 (e.g. organophosphorus compounds) 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.
