Summary of green methods for fabrication of Ag2O NPs nanoparticle materials and their photocatalytic and antibacterial properties

Abstract

Silver oxide nanoparticles (Ag₂O NPs) prepared by green method with plant extracts have a role in the synthesis of materials as reducing and stabilizing agents which have been summarized according to the references. Material characterization measurements investigated include: UV-vis absorption spectrum, XRD, SEM. Investigation of photocatalytic, antibacterial and anti-biofilm properties of Ag₂O NPs were also presented. The crystal sizes of Ag₂O NPs were calculated by the Debye-Scherrer equation with a nanometer size in the range of 6.2-39 nm. The optical band gap energy Eg of Ag₂O nanoparticles was narrow in the range of 1.23-2.86 eV which determined using Tauc equation (based on UV-vis spectrum). The fabricated Ag₂O NPs nanoparticles material has high stability, good photocatalytic properties in decomposing organic dyes and outstanding antibacterial and anti-biofilm properties. It shows that this Ag₂O NPs nano material is a material that is completely capable of being studied more extensively for nanomaterial fabrication to be a good substitute for Ag NPs nano material in similar application fields.
