pH-Transformed ZnO-NPs /NaPTS: The First Room-Temperature Brisk Synthesis of Flavanones in Aqueous Medium

We investigated pH transformed ZnO NPs viz ZnO nanobullets and ZnO nanograins at pH 11 and 12 respectively, synthesized by co-precipitation method. The structural, morphological, chemical, compositional and optical properties of synthesized ZnO NPs were analysed by using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDAX) and Ultra-Violate Visible spectroscopy (UV-Vis). The Noteworthy feature of ZnO NPs in presence of NaPTS leads a speedy formation of flavanones from the reaction of an aldehyde and o-hydroxy acetophenone. Thus, it imparted the first room-temperature brisk synthesis of flavanones in an aqueous medium.
