preparation and characterisation of sno–fe2o3 nanocomposites

Nanocomposites are novel materials which are yet to be explored and utilised in many applications. nanocomposites can be tailored by the volume fraction of the matrix, fibre, and also by the size and shape of the nanomaterial in the composite. preparing nanocomposite with a desired shape and size still remains a challenge. in the present work, sno–fe2o3 nanocomposite was prepared using sol gel route with ferric chloride and tin chloride as precursors. the prepared nanocomposite was characterised by x-ray diffraction (xrd), ultraviolet visible spectroscopy (uv), scanning electron microscope (sem), and fourier transform infrared spectroscopy (ftir). the crystallite size obtained was approximately 60 nm, with a band gap of 3.55 ev. the band gap of the composite could further be tuned with nanosize.
