Synergistic effect of iodine doping and platinum loading on boosting the visible light photocatalytic activity of BiOBr

Publication date: Available online 17 February 2020Source: Inorganic Chemistry CommunicationsAuthor(s): Tongtong Liu, Yawen WangAbstractPlatinum loaded BiOBr with iodine doping photocatalyst (Pt/I-BiOBr) was synthesized to further improve the photocatalytic activity of BiOBr. The photocatalytic test showed the bisphenol A degradation efficiency of Pt/I-BiOBr under visible light was about 93% within 20 min, about 5.8, 1.5 and 1.3 times that of BiOBr, iodine doped BiOBr and platinum loaded BiOBr, respectively. The composition, morphology, optical property and dominant active radical were investigated. Based on the results, a possible mechanism was proposed. Iodine doping and platinum loading played a synergetic effect on broadening the visible light absorption range and increasing the photo-induced carrier separation efficiency of BiOBr.Graphical abstract
