Biocompatible Mn and Cu dual-doped ZnS nanosheets for enhanced the photocatalytic activity under sunlight irradiation for wastewater treatment and embedded with PVA polymer for reusability
This study investigates the synthesis of Mn and Cu-doped ZnS nanosheets via the coprecipitation method, focusing on their structural, optical, photocatalytic, and hemolytic properties. XRD analysis confirmed a cubic structure, with crystallite size decreasing as doping levels increased. TEM identified crumpled nanosheets, while UV–Vis spectroscopy measured bandgaps of 3.98, 3.78, 3.93, and 4.09 eV for the ZM1, ZM2, ZM3, and ZM4 samples, respectively. The ZM3 nanosheets exhibited superior photocatalytic performance, achieving 99 % dye degradation in 110 min under sunlight. Kinetic analysis showed a rate constant of 46.91 × 10−3 min−1 for ZM3. When embedded in a PVA polymer membrane, the ZM3 nanosheets demonstrated 95 % degradation efficiency and excellent reusability. The study also explored the degradation mechanism, effects of dosage and dye variation, and hemolytic activity on human red blood cells, providing a comprehensive understanding of these doped ZnS nanosheets.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
