ABSTRACT

Nanoparticles have superior properties compared to similar particles which have a larger size. Nanoparticle biosynthesis was developed as an alternative method by utilizing reductants from plants so they are more environmentally friendly. This research aims to carry out biosynthesis and characterization of ZnO nanoparticles using binahong (Anredera cordifolia (Ten) Steenis) leaf extract as a bioreductor and stabilizer. ZnO nanoparticles were synthesized from the precursor material Zn(CH3COO)2.2H2O 0.15 M at pH 8 and calcination was carried out at 400oC for 2 hours. Biosynthesis of ZnO nanoparticles with a bioreductant from binahong leaf extract (Anredera cordifolia (Ten) Steenis) produces ZnO particles with an average diameter of 46.07 nm. Secondary metabolites which are thought to act as bioreductors and stabilizing agents from binahong leaf extract are polyphenolic compounds. Synthesis of ZnO nanoparticles produces an elemental composition of 67.8% Zn and 28.2% O with a ratio of 2:1.

Keywords: Bioreductor, Binahong leaves, ZnO nanoparticles.
