Green Synthesis of Zinc Oxide (ZnO) with Extracts taro leaves (Colocasia esculenta L.) using the co-prescription method
This study validates the role of leaf taro extract in the production of ZnO nanoparticles.
Zinc oxide (ZnO) has become a nanomaterial material that attracts attention in a variety of applications such as catalysis, electronics, optoelectronics, and photochemistry. However, conventional ZnO synthesis methods involve toxic chemicals and environmentally unfriendly processes.
Green synthesis is one of the solutions for the synthesis of nanoparticles.
They still use hazardous chemicals. Green synthesis refers to an environmentally friendly approach to synthesizing a variety of materials, including nanoparticles, using sustainable and renewable resources. It involves the use of natural extracts, such as plant extract, as reducing and stabilizing agents in the synthesis process, replacing traditional chemical methods that often involve harmful substances. Green synthesis offers several advantages, including lower environmental impact, cost efficiency, and the production of materials that are environmentally friendly and suitable for biology. It has gained significant attention in a variety of fields, including nanotechnology, material science, and pharmacy, because it is in line with the principles of sustainable development and contributes to the development of greener and more sustainable technologies.
In this study, I explored the potential use of taro leaf extract (Colocasia esculenta L.) as a natural and renewable source for the synthesis of green zinc oxide nanoparticles. (ZnO). The copresipitation method, with sodium hydroxide (NaOH) as a sedimentary agent, is used to facilitate the synthesis process. We investigated the influence of various synthesis parameters, including material ratio, solution pH, reaction temperature, and reaction time, on the formation and properties of the synthesized ZnO nanoparticles. In addition, I have carried out nanoparticle characterization using X-ray diffraction techniques (XRD), electron microscopy scanning (SEM), and Fourier transformation infrared spectroscopy (FTIR).
In the results of this study, taro leaf extract was successfully used in the synthesis of ZnO nanoparticles. UV-Vis measurements showed ZnO formation with a peak absorption at a wavelength of 367 nm and an optical band gap value of about 3.32 eV. Furthermore, the FTIR measurements indicated the presence of phytochemical compounds, such as flavonoids and alkaloids, which showed absorption tapes at 3389,5 cm^1 and 869,7 cm^1, as well as Zn-O bonds at 695,2 cm^1. The XRD measurement results showed that the formed ZnO nanoparticles had a hexagonal crystal structure of wurtzite with an average crystal size of about 25.27 nm. Through SEM analysis, the surface morphology of ZnO is seen to form a hexagonal structure after synthesis using taro leaf extract (Colocasia esculenta L.).
The research findings contribute to the development of sustainable and environmentally friendly methods for the production of ZnO nanoparticles as well as highlight the potential applications of green-based synthesis based on talas leaf extract in a variety of fields, such as catalysis, sensors, and biomedical science.
