Investigating CO₂ storage properties of Pd(II) and Co(II) chelates of a Schiff's base ligand

A new metal complexes are made from the ligands derived from amoxicillin based Schiff's base coordinated with Pd(II) and Co(II) have been synthesized and characterized via different spectroscopic methods. FT-IR spectroscopy have shown a formation of tetrahedral and square planar geometry for Co(II) and Pd(II) complexes, respectively. Surface morphology was inspected via field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM). The Brunauer–Emmett–Teller surface area of the metal complexes samples is about 6.63 to 8.71 m²/g, with pore diameters and volume of 0.030–0.0501 cm³/g and 18.39–22.98 nm, respectively. The quadrupole moment of CO₂ has a great effect on the adsorption capacity as it is highly diffusible of 21.38, 26.16 cm³.g⁻¹ for Co(II) and Pd(II) complex.
