Photocatalytic, biodiesel, electrochemical sensing properties and formylation reactions of ZnO nanoparticles synthesized via eco-friendly green synthesis method

ZnO nanoparticles (NPs) were synthesised through green synthesis method with different concentrations of non-germinated razma (NG) seeds and germinated razma (G) seeds powder as a fuel through. The obtained ZnO NPs were characterised by XRD, FTIR, SEM, TEM analytical techniques. The non-germinated and razma germinated seeds powder ratios are the effect on the structure, morphology, UV concentration, PL emission and photodegradation of dye were analysed. The different structure and shape of NPs were explored for the photodegradation of methylene blue dye. The improved photodegradation of zinc oxide NPs was characteristics of slight crystal dimension, new superficial deficiencies, more band hole and ability to make smaller the electron–hole pair rearrangement. The electrochemical property of the synthesized ZnO NPs has been shown by quantifying dopamine at micro molar concentration levels. In the present study, preparation of biodiesel using ZnO nanocatalyst, Pongamiapinnata oil was used. The chemical process of amines with formic acid in the presence of a ZnO nanocatalyst under solvent-free conditions gives a high yielded protocol for the N-formylation to form the corresponding formamide derivatives.
