High Solar Photocatalytic Degrad ation of A zo Dye ( MB) by Bismuth Fe rrite Synthesized v ia Ultraso und Met hod

From the viewpoint of the utilization of so lar energy, the develop ment of visi ble light-dri ven photo catalyst has attracted mu ch attention in order to water splitting and organic contami nants degra dation especially in the p ast ۱۰ years [۱-۳].Mate rials and m ethods:In this work, pure bismuth ferrite (BFO) as a visible-light photocatalyst has been synthe sized via ultrasonic-assisted method .The struc ture, Size a nd morphology of BF O was exam ined. Then, the photocatalytic degra dation of M B was inve stigated under sun light irradiation.Appa ratus:The ultrasonic irradiation with equipment oper ating at ۲ ۰ kHz (W-۴۵۰ D), X-ray diffrac tometer (XRD, Phlips PW۱۸۰۰), UV–vis spectrophotom eter (Unic o ۲۸۰۰), F ourier transf orm infrare d (FT-IR) spectrometer (Avatar ۳۷۰), Transmission electron micros copy (TEM) were perf ormed.
