“…They can cause serious risks to human health and the natural environment due to their low biodegradability, stability, toxicity, and hazardous potential [ [38] , [39] , [40] , [41] ]. For water treatment, several methods like adsorption, reverse osmosis, foculation, coagulation, evaporation, electro-precipitation, and photocatalytic degradation use UV and solar irradiation [ [42] , [43] , [44] ]. From these methods, photocatalysis has proven to be an important technique for wastewater treatment.…”

Herein, the successful synthesis of ZnO/Fe‐doped Bi2O3 nanocomposite through a microwave‐assisted coprecipitation method is reported. The fabricated materials are comprehensively characterized using X‐ray diffraction, field‐emission scanning electron microscopy, energy dispersive X‐ray analysis, UV–vis, vibrating sample magnetometer, and photoluminescence techniques. The results of the investigation unveil a reduction in crystalline size, a low bandgap of 1.7 eV, and notable improvements in magnetization and surface area (50.63 m2 g−1) upon the incorporation of ZnO and Fe doping into Bi2O3. Remarkably, the ZnO/5% Fe‐doped Bi2O3 composite demonstrates 86.34% degradation of methylene blue (MB) dye within 60 min. Furthermore, this composite exhibits significant antifungal activity, as evidenced by a zone of inhibition diameter of 20 mm against Aspergillus flavus. Ongoing studies are investigating the impact of pH, inorganic ions, scavenger mechanisms, and MB degradation. These findings underscore the synergistic effects of ZnO and Fe, which enhance the absorption of photons that decrease the recombination rate and increase the charge transfer of Bi2O3, contributing to the improved material properties of the ZnO/5% Fe‐doped Bi2O3 composite. This study paves the way for further exploration of the multifunctional properties of ZnO/Fe‐doped Bi2O3 nanocomposites in diverse environmental and biomedical applications.

This study has Zinc oxide (ZnO) nanoparticles (NPs) synthesized from the leaf extract of Costus Afers via a green approach. The synthesized zinc oxide nanoparticle (ZnO NPs) showed excellent adsorption capabilities towards Cd (II) and Pb (II) ions. ZnO NPs were characterized by Fourier Transform Infrared (FT-IR), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD). The formation of ZnO NPs was confirmed by the absorption band at 825cm−1 and 747cm−1. The XRD and SEM analysis show the high purity and hexagonal structure of ZnO NPs with a crystallite size of 83.56 nm. A batch adsorption experiment was employed to examine the process parameters such as the effect of the initial pH of the solution, initial metal ion concentration, adsorbent mass, and contact time on the sequestration efficiency of Cd (II) and Pb (II) ions. The equilibrium isotherm models were studied using Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich isotherm models. The Langmuir adsorption isotherm provided the best fit for the adsorption process with coefficient of determination (R2) values of 0.988 and 0.986 for cadmium and lead (II) ions respectively, indicating a monolayer surface on ZnONPs. The pseudo-second-order kinetics model presented a good fit for the adsorption of Cd (II) and Pb (II) ions on zinc oxide nanoparticles giving a correlation coefficient of 0.989 for Cd and 0.996 for Pb suggesting that chemisorptions are the rate-determining step.
