study of the single step green synthesis of mgo nanoparticles using peanut shell extract for the evaluation of in vitro antibacterial and photocatalytic properties

Among the various available nanoparticles ‘inorganic nanoparticles’ are more promising due to their wide range of application. mgo nanoparticles (mgo nps) is a very important inorganic metal oxide nanoparticle due to their diverse field of applications. there are so many physical and chemical methods are available to fabricate potentially useful mgo nps. the proposed research work highlighted a novel green synthesis method for the fabrication of mgo nps by using waste material peanut shell as a precursor. the green synthesized mgo nps are characterize by the techniques like xrd, sem, ftir, uv-vis spectroscopy. the green synthesized mgo nps are crystalline in nature & the tetragonal structure of mgo nps was determined by xrd, various functional groups present on the surface of the synthesized nanoparticles was determined by ftir and average particle size of green synthesized mgo nps is 25-30 nm, found as result by sem and xrd analysis. two important applications photocatalytic activity and antibacterial activity of the synthesized nanoparticles was investigated in the proposed research work. the green synthesized mgo nps show remarkable photo catalytic activity against the indigo ceramine and rhodamine dyes and approximately after 60 min the photocatalyst completely remove the dyes from the solution. the green synthesized mgo nps show highest antibacterial activity against the pseudomonas aeruginosa (19 mm) bacteria.
