Abstract(s)
Magnetic neat and N-doped carbon nanotubes with different
properties have been synthesized by chemical vapour deposiüon
and tested in the catalytic wet peroxide oxidation of
4-nitrophenol solutions (5 g L') at relatively mild operating
conditions (atmospheric pressure, T = 50 °C, pH = 3)~using a
catalyst load = 2.5 g L-' and [H202]o = 17.8 g L-1. The results
demonstrate that the catalyst hydrophobicity/ hydrophilicity is a
detenninant property in the CWPO reaction, since it affects the
rate ofH202 decomposition. The controlled formation ofreactive
radicais (HO* and HOO*) at hydrophobic surfaces avoids the
formation of non-reactive species (02 and H20), increasing.
