Resumo(s)
Carbon nanotubes (CNTs) bearing a Janus-like structure were
synthesized by chemical vapor deposition considering ethylene
and acetonitrile as carbon and nitrogen sources. The developed
materials were applied as catalyst in the oxidation of 4-nitrophenol
(4-NP) dissolved in a biphasic medium
(water/2,2,4-trimeylpentane) simulating a contaminated oily
wastewater. The CNT prepared using both ethylene and
acetonitrile precursors shows a Janus-structure, leading to the
highest abatement of 4-NP as well as to the highest removal of
TOC, proving to be an alternative towards the removal of lipophilic
pollutants from oily effluents, allowing to reclaim the oily phase.
