Chemically synthesized bimetallic Al-Ni nanoparticles as catalysts for photocatalytic degradation of organic pollutants in wastewater
摘要
Bimetallic nanoparticles are hybrid materials composed of two distinct metals, offering enhanced properties and functionalities compared to their monometallic counterparts. These nanoparticles have garnered significant attention due to their diverse applications in fields such as biomedicine, catalysis, and environmental remediation. The current study focused on synthesizing bimetallic nanoparticles using a chemical method that combined aluminum chloride (AlCl3) and nickel chloride (NiCl2). The synthesized nanoparticles underwent characterization for functional group analysis, surface charge analysis, morphology studies, and crystal structure analysis through scanning electron microscopy (SEM), X-ray diffraction (XRD), and zeta potential measurements. SEM results showed that the nanoparticles had consistent and uniform sizes, while XRD revealed their crystalline structure. Zeta potential measurements determined the surface charge, offering insights into the nanoparticles' stability and potential interactions.The nanoparticles exhibited significant antibacterial activity, with inhibition zones ranging from 8.5 mm to 19 mm against Staphylococcus aureus and Pseudomonas aeruginosa, two prominent pathogens, highlighting their potential for biomedical applications.Additionally, the nanoparticles were used in wastewater treatment, where they effectively removed pollutants and degraded bromocresol green dyewith a degrading efficiency of 87.5% % after 120 min, demonstrating their potential in environmental remediation.Furthermore, the treated wastewater was used as a primary water source for seed germination with mung bean seeds, showcasing the nanoparticles' potential in water conservation and in agriculture. The study's findings suggest that these bimetallic nanoparticles have diverse applications, spanning biomedical and environmental fields, and warrant further exploration.
