Effect of metal decoration on sulfur-based gas molecules adsorption on phosphorene.

ABSTRACT: Based on first-principles calculation, the adsorption of sulfur-based gas molecules (H₂S, SO₂, SO₃) on various metal-decorated phosphorenes is researched systematically. Eleven metals (Li, Na, K, Rb, Cs, Ca, Sr, Ba, Ni, La, Tl) which can avoid the formation of clusters on the phosphorene are considered. Noticeably, all metal decorations can enhance the adsorption strength of phosphorene to sulfur-based gas molecules except for H₂S on Tl-decorated phosphorene. Meanwhile, the adsorption energy (E_ads) shows the trend of E_ads(H₂S) < E_ads(SO₂) < E_ads(SO₃) for the same metal decoration case. In addition, some metal-decorated phosphorene systems exhibit intriguing magnetic and
