What is Effects of functionalized magnetic graphene oxide on the visible-light-induced photocatalytic activity of perovskite-type MTiO3 (M= Zn and Mn) for the degradation of Rhodamine B about?
This work reports the synthesis of a variety of perovskite-type titanates (MTiO 3 , M = Zn, and Mn) and their loading on functionalized magnetic graphene oxide (EDFG) to produce MTiO 3 @EDFG nanocomposites. These materials were fully characterized by FT-IR and Raman spectroscopy, XRD, SEM, TEM, N2 adsorption-desorption, VSM, UV-vis DRS, PL, CV, and EIS techniques. SEM and TEM images of the MTiO 3 @EDFG revealed the homogeneity and distribution of MTiO 3 nanoparticles on the surface of EDFG. UV-vis absorption and PL analyses suggested that the MTiO 3 @EDFG nanocomposites could be used as efficient photocatalysts for the degradation of Rhodamine B (RhB) under visible light irradiation. The results indicated that the photocatalytic activities of the MTiO 3 @EDFG samples were obviously enhanced in comparison to those of bare MTiO 3 . The enhanced photocatalytic activity was mainly attributed to the conglomeration inhibition of MTiO 3 nanoparticles, improved electron transfer between MTiO 3 and EDFG enhanced surface area, and extended absorption range. The possible electron transfer mechanism for EDFG and MTiO 3 interface during the photocatalysis process is also proposed. Furthermore,
