Metal oxide photocatalyst is one of the promising photocatalysts in the water remediation process. The present work is aimed at synthesizing the green production of TiO2 (G-TiO2) nanoparticles from mulberry plant extract. Plant phytochemicals serve a different role to produce the nanophase particles. The bioreductant is safer and noxious free compound for synthesizing the G-TiO2 nanoparticles. The synthesized G-TiO2 nanoparticles in anatase phase and their crystallite size of 24 nm were characterized from X-ray diffraction analysis. The Ti-O bonding and plant derivatives and their reduction were confined from FTIR analysis. The wide bandgap of G-TiO2 nanoparticles (3.16 eV) and their optical characterization were captured from UV-DRS analysis. The spherical surface morphology and their Ti and O elemental configurations were characterized from FESEM with EDX technique. The photocatalytic dye degradation was examined against methylene blue dye, and their pseudo-first-order kinetics were evaluated. The cyclic experiments declared their catalytic potential. The bacterial resistance of G-TiO2 nanoparticles was examined against gram-positive and gram-negative bacteria. Hence, the catalytic potential and bacterial stability of G-TiO2 nanoparticles are the powerful candidate for water remediation and biomedical applications.

Environmental nanotechnology has received much attention owing to its implications on environmental ecosystem, and thus is promising for the elimination of toxic elements from the aquatic surface. This work focuses on Cu-doped ZnSe nanoparticles using the co-precipitation method. The synthesized Cu-doped ZnSe nanoparticles were examined for structural, optical, and morphological properties with the help of XRD, FTIR, UV/vis diffuse reflection spectroscopy (DRS), FESEM, TEM, and XPS. The synthesized Cu-doped ZnSe nanoparticles revealed the presence of Cu2+ in the ZnSe lattice, which has been shown to take a predominant role for enhanced catalysis in the Cu-doped ZnSe nanoparticles. The synthesized Cu-doped ZnSe nanoparticles were investigated for their catalytic and antibacterial activities. The 0.1 M copper-doped ZnSe nanoparticles exhibited the highest rate of degradation against the methyl orange dye, which was found to be 87%. A pseudo-first-order kinetics was followed by Cu-doped ZnSe nanoparticles with a rate constant of 0.1334 min−1. The gram-positive and gram-negative bacteria were used for investigating the anti-bacterial activity of the Cu-doped ZnSe nanoparticles. The Cu-doped ZnSe nanoparticles exhibited enhanced photocatalytic and antibacterial activity.

The innovation and development of water purification methods have been at the center of extensive research for several decades. Many nanoparticles are frequently seen in industrial waste water. In this research, zinc oxide nanoparticles (ZnO) were synthesized following an autocombustion method with and without honey capping. Structural crystallinity and bonding structure were examined via X-ray diffraction (XRD) analysis and Fourier transform infrared (FTIR) spectroscopy. Optical behavior was analyzed using ultraviolet–visible (UV–Vis) spectroscopy and photoluminescence (PL). Size estimation and surface morphology were studied using scanning electron microscopy (SEM), while energy-dispersive spectroscopy (EDS) was performed to analyze the sample purity and elemental composition. The photocatalytic degradation of methylene blue (MB) by ZnO was assessed as it is an efficient water treatment process with high potential. The biological activity of ZnO nanoparticles was also investigated in terms of antibacterial and antifungal activities against different bacterial and fungal species. Surprisingly, the as-synthesized ZnO nanoparticles were found to be substantially bioactive compared to conventional drugs. Honey-mediated nanoparticles displayed 86% dye degradation efficiency, and that of bare ZnO was 60%. Therefore, the involvement of honey in the synthesis of ZnO nanoparticles has great potential due to its dual applicability in both biological and environmental remediation processes.
