Photodegradation of methylene blue using phyto-mediated synthesis of silver nanoparticles: effect of calcination treatment

In this study, discrete Ag⁰ nanoparticles (10–30 nm) were synthesized by a simple electrochemical method in Cymbopogon nardus leaves extract as a medium. The leaves extract remarkably reduce the Ag⁰ ion to produce Ag⁰ nanoparticles without any agglomeration. Its crystallinity, morphology, and functi...
