Photo Fenton degradation of phenol by CdS/rGO/Fe2+ at natural pH with in situ generated H2O2
Abstract The application of photo Fenton process is restricted by the acidic pH and additional hydrogen peroxide (H2O2) In order to overcome these drawbacks, a photo Fenton system of CdS/rGO/Fe2+ which can perform at natural pH with in situ generated H2O2 has been successfully developed. Highly efficient photo Fenton degradation of phenol was achieved under the visible light irradiation via the CdS/rGO/Fe2+ system. Experimental results showed that phenol could be degraded completely in 1 h at natural pH. The plentiful in situ generation of H2O2 was further proved to act as an important role in phenol degradation with the addition of Fe2+ The advantages of degradation at natural pH with in situ generated H2O2 can provide a new prospective to the environmental friendly Fenton process.
