摘要: Abstract Now a day’s, Calcium carbonate (CaCO3) is ineluctable filler in emerging industrial fields. Polymer-mediated CaCO3 nanocomposites are dreadfully useful wide range of applications. To achieve such (NCs), the present study, (without polymer), PMMA, PEG and PVP/CaCO3 NCs have been successfully synthesized by biomimetic method using natural limestone rock as crucial source. Synthesized products were characterized FTIR, XRD, SEM-EDS, TEM, UV–Vis DRS PL techniques to know mineralogy, morphology, crystallites size, band gap energy emission characteristics. The size final product about 20–30 nm. It has monodispersed, spherical shape porous like structure. value (3.15–3.36 eV) exhibits good luminescence intensity blue region. subjected supercapacitor performance photocatalytic activities effectiveness product. Achieved characteristics show that may be used for various This synthesis Eco-friendly hot chemical free. recommends instead huge chemicals which source, getting nano composite extensive requirements with lesser cost.
