Calcium oxide Nanoparticles

Calcium oxide Nanoparticles

Calcium oxide nanoparticles have found various functions, such as in catalysis, adsorption, water purification and also as antibacterial agents. CaO Nanoparticles is of particular interest as it is considered safe for humans and animals. There are many reports on the preparation of CaO nanoparticles by chemical methods. However, only a few biogenic synthetics are described in the literature. In this work, CaO nanoparticles were synthesized from papaya leaf extract and green tea. The prepared CaO nanoparticles were then characterized using UV-Vis spectroscopy, Fourier infrared transformation (FT-IR), X-ray powder diffraction (XRD) studies, scanning electron microscopy (SEM) techniques. Functions such as antibacterial and photocatalytic activity have been studied. CaO nanoparticles have received considerable attention due to their unusual properties and potential functions in various fields. Calcium oxide nanoparticles, in particular, has a high basicity of being cheap, and is non-corrosive, economically harmless and easy to handle compared to homogeneous basic catalysts. In addition, they require only mild reaction conditions to produce high yields of products in short reaction times, compared to traditional catalysts, and are also recyclable. More recently, CaO nanoparticles have been used as an active catalyst in many chemical transformations, such as: Cr (VI) adsorption from aqueous solutions, sunflower oil translocation, and removal of toxic heavy metal ions in water, artificial photosynthesis and palm trasesterification. CaO nanoparticles, as an effective, non-explosive, ecological, non-volatile, recyclable and manageable catalyst can be used to catalyze many organic transformations.
