研究目的
Investigating the green synthesis of ZnO nanoparticles using Pithecellobium dulce peel extract for their antifungal and photocatalytic activities.
研究成果
The green synthesis of ZnO NPs using P. dulce peel extract is an efficient, eco-friendly method. The NPs showed good photocatalytic activity in degrading MB and significant antifungal activity against A. flavus and A. niger, suggesting potential applications in environmental remediation and antimicrobial treatments.
研究不足
The study focuses on the synthesis and preliminary testing of ZnO NPs for antifungal and photocatalytic activities. Further studies are needed to explore their applications in environmental science and nanotechnology.
1：Experimental Design and Method Selection:
The synthesis of ZnO NPs was performed using Pithecellobium dulce peel extract as a capping and stabilizing agent. The NPs were characterized using UV-vis spectroscopy, XRD, SEM, and TEM.
2：Sample Selection and Data Sources:
The peel of P. dulce was collected from Puttuthakku Forest, Vellore district, Tamil Nadu, India. Zinc acetate and MB were procured from AVRA Chemicals, Hyderabad, India.
3：List of Experimental Equipment and Materials:
UV-vis spectrophotometer, X-ray diffractometer, scanning electron microscope, transmission electron microscope, muffle furnace, centrifuge.
4：Experimental Procedures and Operational Workflow:
The peel extract was mixed with zinc acetate solution, and the formation of ZnO NPs was monitored by UV-vis spectroscopy. The NPs were then characterized and tested for photocatalytic and antifungal activities.
5：Data Analysis Methods:
The size of the NPs was determined using the Scherrer equation from XRD data. Photocatalytic activity was analyzed using a pseudo-first-order-kinetics equation.
