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.
