BaTiO3@rGO nanocomposite: enhanced photocatalytic activity as well as improved electrode performance

M. A. Majeed Khan et al.

Summary: The BaTiO3 nanoparticles and BaTiO3@rGO nanocomposite were successfully prepared and characterized through various analysis techniques. The dielectric properties of the samples were studied, and the photocatalytic performance of the BaTiO3@rGO nanocomposite was found to be superior to the nanoparticles, possibly due to its larger surface area and efficient separation of photo-excited electron-hole pairs.

Poly(pyrrole-co-styrene sulfonate)-encapsulated MWCNT/Fe-Ni alloy/NiFe2O4 nanocomposites for microwave absorption

Yan Cao et al.

Summary: The MWCNTs/Fe-Ni alloy/NiFe2O4 (M/F/N) nanocomposite was prepared through a hydrothermal method and then coated with poly(pyrrole-co-styrene sulfonate) (PP@M/F/N) via in-situ polymerization. The nanocomposite exhibited excellent microwave absorption properties in the X band frequency range, with a minimum reflection loss of -85 dB at 12 GHz for 2 mm thickness. Coating with the copolymers improved electron transport, impedance matching, interfacial polarization, and attenuation ability of the composite. This study provides a facile and efficient method for preparing magneto-electric nanocomposites as promising candidates for microwave absorption applications.
