Realisation of CdS/Mn ₃ O ₄ nanocomposites for potential photocatalytic applications

The present work reports the realisation of high‐quality crystalline CdS/Mn ₃ O ₄ (CM) nanocomposites by a simple cost‐effective chemical method in air atmosphere. The authors have performed theoretical calculations and experimental analysis in order to understand the synthesised nanocomposites. X‐ray diffraction results showed that the CM nanocomposites were cubic and orthorhombic mixed structure which is in good agreement with the theoretical studies. Field emission scanning electron microscopy images of CM confirmed the formation of well distributed nanocomposites. The outcomes of DFT calculations provide results for the bandgap calculation of pure CdS, Mn ₃ O ₄ and the CM nanocomposites. Photoluminescence studies with interesting visible light absorption demonstrated the great potentiality of the as‐synthesised nanocomposites towards photocatalytic applications that could be a detailed research scope for the authors’ future studies.
