Abstract


A nanostructured Co3O4/BiVO4Composite photoanode. synthesized using a facile electrospinning method, applied. photoelectrochemical(PEC)Degradation. of all EDCs(BPA). Assistance. peroxymonosulfate(PMS).REsults show, PMS obviously enhanced. photoelectrocatalytic degradation. BPA. Co3O4/BiVO4Composite photoanode.When at 0. 25 V bias potential, Visible Light Irradiation. 2 mmol in L-1PMS Addition96%. BPA. removed within 2 h, Corresponding Kinetic Constant. 0. 471 4 min-1.. Effects. initial PMS concentration, bias potential. BPA degradation..REsults show, BPA could. efficiently degraded at lower PMS concentrations, lower bias Potentials.SOIn ·4-, In OH. identified as. primary free radicals using an electron spin resonance Spectrometer.Free Radical Quenching experiments. carried out, The photogenerated holeSOIn ·4-, In OH proved. responsible. BPA oxidation.There. no metal ion leaching detected. solution after. ReactionsWhich means. secondary pollution could. avoided.
