Synthesis and characterization of nanocomposites Fe3O4-ZnO

Bio‐Based Hybrid Catalysts for the Synthesis of Pharmacologically Active Xanthenes

“…[12a] An extremely sharp band was seen at 640 cm À 1 for FT-IR spectra corresponding to stretching vibrations of the SbÀ O bond, suggesting a reaction between magnetic nano linear dextrin and antimony. [30] The Fe 3 O 4 @NLD/Sb + 5 (c) and Fe 3 O 4 @NLD (b) XRD patterns were compared to the standard Fe 3 O 4 (a) XRD pattern, [31] and three samples showed the characteristic Fe 3 O 4 peaks. An intense characteristic diffraction peak can be seen for the (400), (311), and (220) planes.…”

An intense characteristic diffraction peak can be seen for the standard patterns of Fe 3 O 4 (JCPDS card #00‐001‐111) at 2θ=74.73°, 63.06°, 57.23°, 53.73°, 43.34°, 35.75°, and 30.38°, respectively, which correspond to (533), (440), (511), (422), (400), (311), and (220) planes.…”
