Visible light-induced photocatalysis–self-Fenton degradation of P-Clphoh over graphitic carbon nitride by a ... - EurekAlert
The article published in the Transactions of Tianjin University reports on a novel photocatalyst, 5%Fe-4PEI-CN, in the field of photocatalysis by Professor Li Hexing, an expert in the field. This catalyst is based on graphene-like carbon nitride (CN) doped with polyethyleneimine (PEI) and iron (Fe) species. The relationship between the catalyst's structure and catalytic efficiency is explored. The study found that PEI-modified CN exhibited significantly enhanced capability in generating hydrogen peroxide (H2O2) under visible light catalysis, with a maximum production rate of 102.6 µmol/L, which is 22 times higher than that of pristine CN. Additionally, the research demonstrates that the combined photocatalytic oxidation and Fenton-like oxidation processes exhibit remarkable degradation efficiency towards p-chlorophenol (p-ClPhOH), indicating promising applications in the treatment of recalcitrant organic wastewater.
