Construction Of Agbio3/G-C3n4 Nanocomposites With Enhanced Photocatalytic Activity And Their Application In The Degradation Of Bisphenol A

In this paper, AgBiO3 and g-C3N4 materials were prepared by the ion-exchange method and calcination method, respectively. Their composite materials with different compositions were prepared by changing the dosage of raw materials during the synthetic process. The prepared nano-composite materials were utilized to degrade bisphenol A (BPA) under visible light irradiation. By comparison, 50 wt.% AgBiO3 in AgBiO3/g-C3N4 (ABC-50) owns the supreme photocatalytic activity with 95.75% degradation efficiency of BPA and the degradation process was proven to follow the pseudo-first-order kinetics. In addition, the oxidative species of O-center dot(2)- and h(+) and OH were found to play equal roles in the photocatalytic reaction process.
