WebABSTRACT In the present study, ability of Al12N12 nanocluster as a new adsorbent for boron trichloride is studied by using density functional theory (DFT) calculations. Two distinct relaxed geometries of Al12N12-BCl3 complex are located. The dominant configuration (B) involves chemisorption of BCl3 on aluminum nitride nanocluster with an adsorption …
WebDue to chemical bonding, enthalpy of adsorption of chemisorption is high nearly 80 to 240 kJ/mol. Physisorption of gas adsorbed at a lower temperature may be converted into chemisorption at a higher temperature. Chemisorption depends on the surface area. As the surface area of the adsorbent increases, chemisorption also increases.
