Abstract |
ZnO-Bi2O3-Graphitic Carbon Nitride/H2O2 system degraded 93% of Indigo Carmine in aqueous solution (50 mg/L) under visible irradiation in 180 min. The heterostructural material of ZnO-Bi2O3-Graphitic Carbon Nitride was prepared using co-precipitate method at 80 oC. The mechanism of photocatalytic degradation of Indigo carmine shows the responsible species for the degradation of Indigo carmine is the hydroxyl radicals which were generated from the reaction of e- and h+ with H2O2. Besides, the kinetic of the photocatalytic process was detailed. The prepared catalyst displayed excellent stability during four cycles. These results demonstrate that the ZnO-Bi2O3- Graphitic Carbon Nitride/H2O2 system may become a promising technique for removing harmful organic dyes through advanced oxidation processes.
