A Nanocomposite of ZnO and N,P‐Co‐Doped Carbon Dots for the Photocatalytic Degradation of Various Dyes and their Kinetic Study

“…Specifically, the determined bandgap values are 3.5 eV and 2.0 eV for ZnO nanoparticles and the ZnO‐NPCdots nanocomposite, respectively. The reduction in the bandgap observed in the ZnO‐NPCdots nanocomposite is attributed to the generation of deep impurity energy levels within the forbidden band [14] . This phenomenon leads to the modulation of energy level structures and photoelectrochemical properties, consequently enhancing the number of active sites and improving phototocatalytic activity.…”

ZnO based 0–3D diverse nano-architectures, films and coatings for biomedical applications

“…Some reviews are focused on ZnO/polymer nanocomposites and their biomedical applications. 52,53 Weng et al 54 reported on stimuli-responsive ZnO-based nanomaterials in biomedical applications, whereas Sun et al 55 reviewed a ZnO based photocatalyst for biomedical applications. This review is intended to comprehensively report on recent advances in the synthesis and engineering technologies involved in ZNS based 0–3D diverse nano-architectures, thin film growth, coatings, tailoring of their properties, characterization, and device fabrication in addition to the multifunctional biomedical applications.…”

Zinc Oxide/Iron Oxide Nanocomposites for Photodegradation and Adsorption of Pollutants in Water

“…13 Undoubtedly, ZnO nanoparticles (NPs) are by far the most widely used photodegradation agent, as demonstrated by the huge volume of literature currently available. 14 However, some limitations to this semiconductor are recognized that partially hinder its applicability in the water remediation context. One of them is the complex procedure needed to achieve the separation of ZnO NPs from the treated media.…”
