Electron-rich oxygen enhanced Fe-doped g-C3N4 mediated Fenton-like process: Accelerate Fe(III) reduction and strengthen catalyst stability

Both the ≡Fe(III) reduction and the catalyst stability are the main obstacles limiting the application of such Fe-doped Fenton-like catalysts in endocrine disruptors removal. Herein, oxygen was introduced to the Fe-g-C3N4 to fabricate a newly Fe–O-doped catalyst FeCA-g-C3N4. The pseudo-first-order rate constant for bisphenol A (BPA) degradation in FeCA-g-C3N4 system is 2.6 times higher than that in the traditional Fe-doped g-C3N4 (FeCl3-g-C3N4)...
