Abstract
The adsorption properties of N2 molecules on anionic, cationic, and neutral Wn clusters (n = 1 - 5) are studied using the density functional theory with the generalized gradient approximation and with the hybrid functional. Adsorption energies accompanying charge population and vibrational analysis are used to characterize the adsorption properties of N2 on Wn clusters with different sizes and charge states. Our calculations show that all the W clusters can adsorb one N2 molecule with adsorption energy about 0.29-1.72 eV at B3LYP level, and 0.35-2.05 eV at PW91 level, by forming a linear or quasi-linear structure W-N-N.
