Previous issue date: 2017-07-31 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / Neste trabalho est? sendo apresentado o processo de remedia??o de poluentes
em meio aquoso usando micromotores de PEDOT/Pt, ZrO2-GO/Pt e
micromotores Janus de magn?sio no tratamento de captura de CO2, remo??o de
agentes neurol?gicos (como os compostos organofosforados) usados em
bombas de natureza qu?mica e na remo??o do nitrito, respectivamente. 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.
