Peroxy Radical Formation from Cu2O/poly(acrylonitrile) Nanofibers and Hydrogen Peroxide
Cu2O/poly(acrylonitrile) nanofibers as a heterogeneous catalyst were successfully fabricated. The prepared samples were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The Cu2O/PAN nanofibers showed excellent catalytic performance.
The poly(acrylonitrile) influence on the Cu2O Fenton-like properties was also investigated. Electron Paramagnetic Resonance (EPR) confirmed that the peroxy radical (HOO•) was the primary active species in the Cu2O/poly(acrylonitrile) nanofibers/H2O2
system which was completely different from the traditional Cu2O Fenton-like reaction. Furthermore, a possible mechanism of catalytic oxidation was proposed which may be attributed to the influence of the cyano group.
