Abstract The adsorption of CO 2 on a nano-calcium oxide (nano-CaO) adsorbent was investigated under different conditions temperature and supply pressure, considering kinetic, isotherm, thermodynamic parameters. CaO is crystalline material with high surface area nanosized particles porosity, which showed rapid initial rates in the moderate range studied. well described by pseudo-second-order int...

In this research, a simple oxidation chemical process was applied for the synthesis of novel PANI@ZnO nanocomposite. The prepared nanocomposites were characterized by XPS, XRD, FTIR, SEM, TGA and N2 adsorption–desorption isotherms. Thereby, highest SBET values (about 40.84 m2 g?1), total mesoporous volume 3.214 cm3 g?1) average pore size 46.12 nm). Afterwards, nanomaterial as nanoadsorbent adso...
