The mechanism of CO oxidation by O2 on a single Au atom supported on pristine, mono atom vacancy (m), di atom vacancy (di) and the Stone Wales defect (SW) on single walled carbon nanotube (SWCNT) surface is systematically investigated theoretically using density functional theory.

Based on the concept of density of states (DOS) engineering, we theoretically designed a pseudo-Tc material (Mo–Ru alloy) and investigated its electronic structure, phase stability and catalytic activity by using density functional theory.

The Spin-Polarized Conceptual Density Functional Theory (SP-CDFT) provides a local reactivity descriptor that after being assessed on the catalytic site (Fe) tends to be proportional to catalytic activity in a better way than the net electric charge computed on the same site. For this aim three 2,6-bis(imino)pyridil iron(iii) cationic catalysts, used for the polymerization of ethylene, were studied.
