Abstract

The aim of the present work is to synthesize environmentally friendly nanomaterials, which are viable and better alternative method for distinct applications. The co-precipitation method is used for the preparation of BaSO₄ nanostructures with the influence of Azedarach indica leaf extracts as organic stabilizing agents. For synthesizing nanostructures, two different solvents (Ethanol and deionized water) were taken along with distinct molar concentration (0.05 and 1.0 M) are investigated by various characterization techniques. Initially, the XRD pattern revealing the orthorhombic phase structure was well-matched with JCPDS file. Next, FTIR transmission spectrum confirmed the presence of Ba and SO₄ stretching vibration molecules. The morphological studies of SEM evidenced at 1 and 2 µm scale level the successful preparation of rice grain (or nanorods) like nanostructures with the average diameter of ~73.5 nm (ethanol) and 222 nm (DI water). Also, the prepared sample elements were evidenced by the EDX spectra. This employed experimental study revealed that the DI water solvent with higher molar concentrations plays a crucial role in the morphology and size of BaSO₄ nanostructures. In the future, these nanocrystalline materials could be find applications in antimicrobial activities.
