Description
Summary:Magnetic porous clay heterostructure (magnetic PCH) was successfully synthesized using a simple precipitation method of applying magnetite onto a PCH surface. X-ray techniques were used to confirm the presence of magnetite in the composite. The magnetite particles, as investigated by the transmission electron microscopy, were spherical nanoparticles (~12.07 nm). The magnetic PCH exhibited characteristics of mesoporous material type IV, similar to PCH. Significant enhancement of the magnetic and dielectric properties in the high frequency range was also observed.
