Controlled synthesis and characterization of electron rich iron(iii) oxide doped nanoporous activated carbon for the catalytic oxidation of aqueous ortho phenylene diamine

Abstract

A Fe-NPAC400 catalyst was prepared, characterized and used as a heterogeneous Fenton catalyst to degrade and mineralize aqueous O-phenylene diamine.

Fe3−Cu O4 as highly active heterogeneous Fenton-like catalysts toward elemental mercury removal

“…It can therefore be concluded that the Fenton-like solution is generally regulated in pH 6-8, Fe 3Àx Cu x O 4 catalysts are suggested to be preferably applied at neutral medium. The result is in good agreement with the founding from Karthikeyan et al (2014) who demonstrating that a heterogeneous iron-modified catalyst only has a highest catalytic activity at pH 6. Considering the complexity of solution pH effects on Å OH production, more research needs to be performed in the future to clarify the mechanism of H 2 O 2 decomposition.…”

Cu and Fe oxides dispersed on SBA-15: A Fenton type bimetallic catalyst for N,N -diethyl- p -phenyl diamine degradation

“…The Fe 2p 3/2 XP binding energy of 710.55 eV (Fig. 5a) was consistent with the presence of Fe 2 O 3 [36], although the low signal intensity prohibited clear observation of the anticipated shake-up satellite around 719 eV. The corresponding Cu 2p XP spectrum (Fig.…”

In situ generation of hydroxyl radical by cobalt oxide supported porous carbon enhance removal of refractory organics in tannery dyeing wastewater

“…However, cobalt oxide could cause environmental problems if it was present in treated water. However metal oxide supported NPAC would provide a good solution [23]. The heterogeneous Fenton like catalysts were found to be efficient for the degradation of various organic compounds present in domestic or industrial wastewater.…”
