The synthesized meso porous CuO was characterized with XRD, TGA, SEM and BET. The result revealed that the synthesized porous CuO has high mesoporous surface area and crystal structure with uniform sized spherical crystal particles. The specific surface area (S<sub>BET</sub>) of synthesized CuO was found to be 153.46 m<sup>2</sup> g<sup>-1</sup> with a total pore volume (V<sub>p</sub>) of 0.1516 cm<sup>3</sup> g<sup>-1</sup> and average pore size of 3.9 nm, which was much higher than that of commercial CuO (S<sub>BET</sub>, 7.6 m<sup>2</sup> g<sup>-1</sup>; V<sub>p</sub>, 0.01 cm<sup>3</sup> g<sup>-1</sup>). The CO<sub>2</sub> studies also revealed that the synthesized CuO nanoparticles have maximum CO<sub>2</sub> adsorption of about 75 mg/g (7.5 wt %) at room temperature and pressure.</p> ER -
