In this work CaCO3 nanoparticles and CaCO3-Ag nanocomposites were synthesized from calcium carbonate mine by three various procedures. Hydrothermal, sono-chemical and micro-wave irradiation were carried out and their effects on the morphology and properties of nanoparticles were studied. Photocatalytic performance was estimated for degradation of methyl orange toxic dye under visible light and indicates high decolorization. Results indicate that, CaCO3-Ag nanocomposite show photocatalytic suitable efficiency. The presence of Ag in the nanocomposite facilitates photocatalytic decolorization reaction. The effect of different parameters such as amount, radiation time and source of photon was also investigated. This work presents a cost-effective photocatalyst for purification of toxic aromatic dyes from water. Antibacterial activity was investigated by degradation of E-coli bacteria in the presence of CaCO3–Ag nanocomposite.
