NOVELTY - Light-Fenton system comprises graphitic carbon nitride/reduced graphene oxide (g-C3N4/rGO) added to the Fenton system in the ratio r:g-C3N4 of 1:0.15. USE - The light-Fenton system is useful for producing hydrogen peroxide (claimed). ADVANTAGE - The light-Fenton system uses graphene modified g-C3N4 having good electrical conductivity, reduces electron enthalpy hole recombination, enhances oxidation efficiency and continuously generates H2O2 and catalyst increases rate of wastewater degradation.
