| 摘 要： | 运用第一性原理,研究了N2O在Yn(n=2-7)团簇表面吸附机理.结果表明:N_2O吸附于Yn(n=2-7)团簇表面时,不需要克服任何能垒而自然解离.吸附导致了主团簇Y原子平均键长增大,体系表现出了巨大的吸附能(约为8-10 e V).吸附对体系化学活性的影响具有一定的尺寸依赖性.在所有团簇中,Y_6N_2O吸附能最大,化学性质最稳定.

| Abstract: | The electronic properties of adsorption mechanism of N2O molecule on Yn (n=2-7) clusters have been studied with first-principle calculation. The results show that the N2O molecule dissociates on the Yn (n=2-7) surface without overcoming any energy barrier. The average bond length between Y-Y atoms of the corresponding host Yn cluster is elongated due to the N2O adsorption, and the adsorption energy exhibits huge value (8-10eV). The exhibition of chemical activity varies along with the change of cluster size. Y6N2O complex has the biggest value of adsorption energy, as well as the highest chemical stability. |
