Enrichment of optical, magnetic and photocatalytic properties in PVP capped CdO/SnO2 nanocomposites synthesized by microwave irradiation method

Abstract

In this research study, the PVP capped CdO/SnO2, hybrid CdO/SnO2, and pure CdO nanocomposites were synthesized using simple chemical reaction and microwave irradiation method. The semantic approach studies the structural, morphological, elemental composition, optical, magnetic, thermal properties. XRD studies confirm that the particle size decreased in PVP capped CdO/SnO2 and CdO/SnO2 nanocomposites compared to pure CdO sample. Also, the existence of diffraction peaks of both CdO and SnO2 in fabricated hybrid CdO/SnO2 nanocomposite proves that the lattice combination of CdO and SnO2. The SEM and TEM images conclude that after doping of SnO2 and PVP with CdO nanoparticles, the particle structure transformed to rod-like morphology. FTIR spectrum of SnO2 and PVP: SnO2 doped CdO and their functional groups were studied. And also the presence of elemental composition analyzed by EDS spectrum. The UV absorption spectra results of SnO2 and PVP: SnO2 doped CdO states the red-shifted in the bandgap. An enhanced photocatalytic activity is observed in SnO2, PVP doped CdO nanocomposites. The thermal analysis curve of TGA and DTA confirms the thermal stability of synthesized nanocomposites. The CdO sample exhibits the ferromagnetic property. And Antiferromagnetism property is observed in SnO2, PVP doped CdO nanocomposites.
