RETRACTED ARTICLE: Facile green synthesis of CaO NPs using the Crataegus pontica C.Koch extract for photo-degradation of MB dye

In this research, a novel synthesis of CaO nanoparticles via a green, environmentally, and economical method is developed. Crataegus pontica C.Koch leaves extract was used as a green reducing and stabilizing agent to synthesize the calcium oxide nanoplates ranging from 40 to 65 nm. The synthesized C...

Description
Summary:In this research, a novel synthesis of CaO nanoparticles via a green, environmentally, and economical method is developed. Crataegus pontica C.Koch leaves extract was used as a green reducing and stabilizing agent to synthesize the calcium oxide nanoplates ranging from 40 to 65 nm. The synthesized CaO NPs are characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and Fourier transform infrared (FT-IR) spectroscopy. The CaO NPs were evaluated successfully for photocatalytic degradation of methylene blue (MB) dye with 98.99% degradation efficiency under sunlight by a simple technique. The recoverability and reusability of the CaO photocatalyst were considered under the optimized reaction conditions, which are showed high chemical stability after at least five runs.
