Core-shell Fe3O4@SiO2@PANI composite: Preparation, characterization, and applications in microwave absorption

Preparation of magnetic silica supported Brønsted acidic ionic liquids for the depolymerization of lignin to aromatic monomers

“…27,28 No other diffraction peaks are found, indicating the high purity of the as-prepared Fe 3 O 4 . 29 Similar to the XRD pattern of Fe 3 O 4 , the XRD pattern of Fe 3 O 4 @ SiO 2 shows the characteristic peaks of Fe 3 O 4 only, which reveals a homogeneous dispersion of the amorphous SiO 2 shell and no other characteristic peaks are found. In the meanwhile, Fe 3 O 4 particles are well retained in the silica matrix with no phase change, indicating the successful preparation of the carrier Fe 3 O 4 @ SiO 2 .…”

Ternary Fe3O4/reduced graphene oxide/phytic acid doped polyaniline hybrid based supercapacitive electrode with high capacitance retention and good cycling stability

“…88-0866), respectively, could be detected for both F-RGO and F-RGO-p-PANI-II. 47 Meanwhile, weak diffraction peaks at 2 θ = 14.9°, 18.4° and 25.38°, corresponding to the (011), (020) and (200) crystal planes of PANI, could also be found in the pattern of the F-RGO-p-PANI-II hybrid. 48…”

A novel surface molecularly imprinted polymer electrochemical sensor based on porous magnetic TiO2 for highly sensitive and selective detection of tetracycline

“…4b). 53 The absorption peaks from 400 cm −1 to 700 cm −1 can be ascribed to Ti-O-Ti and Ti-O telescopic vibration absorption peaks, indicating the formation of TiO 2 layers (Fig. 4c).…”
