ZnO nanostructured materials and their potential applications: progress, challenges and perspectives.

Extensive research in nanotechnology has been conducted to investigate new behaviours and properties of materials with nanoscale dimensions. ZnO NPs owing to their distinct physical and chemical properties have gained considerable importance and are hence investigated to a detailed degree for exploitation of these properties. This communication, at the outset, elaborates the various chemical methods of preparation of ZnO NPs, , the mechanochemical process, controlled precipitation, sol-gel method, vapour transport method, solvothermal and hydrothermal methods, and methods using emulsion and micro-emulsion environments.

Novel CuO/MnO/ZnO nanocomposite with superior photocatalytic activity for removal of Rabeprazole from water.

In this work, a nanohybrid of CuO/MnO/ZnO was generated through a simple hydrothermal based procedure. The CuO/MnO/ZnO nanohybrid has been characterized using X-ray diffraction, transmission electron microscopy high resolution transmission electron microscopy, X-ray photoelectron spectroscopy, scanning electron microscopy and energy dispersive X-ray analysis. UV-visible spectrophotometry and photoluminescence techniques allowed evaluation of optical properties that additionally suggested the prevalence of strong interfacial interaction between the three moieties of the nanohybrid and suppressed electron-hole recombination.

Novel magnetically retrievable InO/MoS/FeO nanocomposite materials for enhanced photocatalytic performance.

The current work involves synthesis of hybrid nanomaterial of InO/MoS/FeO and their applications as photocatalysts for disintegration of esomeprazole under visible light illumination. The data emerged from various analyses testified to the successful construction of the desired nano-scaled hybrid photocatalyst. Tauc plot gave the band gap of InO/MoS/FeO to be ~ 2.
