Nanostructured gas sensors find diverse applications in environmental and agricultural monitoring. Herein, adsorption of phosgene (COCl2) on pure copper-decorated B12N12 (Cu–BN) is analyzed through density functional theory (DFT) calculations. Adsorption copper results two optimized geometries, named Cu@b66 Cu@b64, with energies −193.81 −198.45 kJ/mol, respectively. The adsorption/interaction COCl2 BN nanocages are −9.30, −6.90, −3.70 kJ/mol G1, G2, G3 respectively, whereas the interaction...
