Focusing at efficient Cefixime (CEFX) removal, a delicate ultrathin-Bi2WO6 (UBWO) stacked quasi-CoFe2O4
binanosheets (BT) were meticulously designed and integrated with spherical MnWO4 (MWO) and carbon
quantum dots (CQDs), forming a n-p-n CQDs@MWO/CFO:UBWO nanohybrid. XRD, XPS, TEM and other systematic
analysis demonstrated the vertically aligned layer by layer assembly of UBWO:CFO BT, and a shift in the
highly exposed (211) facet of UBWO after nanohybrid formation as well as large surface area (323.33 m2/g) was
achieved. UV–vis DRS, PL and EIS proved high separation efficiency, prolonged life time and photogeneration of
more charge carriers with absorption of full light spectrum. As expected, the optimized 5 %CQDs@0.25MWO/
0.1CFO:UBWO nanohybrid displayed excellent visible light absorption and outstanding CEFX photodegradation
Herein, we report the Ohmic and Schottky junction (O-S scheme) Ag-r-GO-CuFe2O4-Fe3O4 nanocomposite (Ag-r-
GO-CFO-FO NCs) for effective photocatalytic activity against organic pollutants.…
