Abstract

Using first principle calculations, we have investigated the adsorption of CO gas on various metal-decorated phosphorene. Almost all of the metals were considered to decorate phosphorene. By comparing binding energy ( ) and cohesive energy ( ), only 10 metals (Li, Na, K, Rb, Cs, Ca, Sr, Ba, Pd, and La) can stably decorate phosphorene and avoid clustering. CO adsorptions on these metal-decorated systems were calculated, and the mechanism of interaction between CO and metal atoms was analyzed in detail. shows a significant improvement after metal decoration, excerpt for Rb and Cs. The results imply that Li-, Na-, K-, Ca-, Sr-, Ba-, and La-decorated phosphorene could be used as CO elimination or reversible CO storage.

摘要

通过第一性原理计算，我们研究了CO气体在各种金属修饰的磷烯上的吸附情况。几乎考虑了所有用于修饰磷烯的金属。通过比较结合能（）和内聚能（），只有10种金属（锂、钠、钾、铷、铯、钙、锶、钡、钯和镧）能够稳定地修饰磷烯并避免团聚。计算了CO在这些金属修饰体系上的吸附情况，并详细分析了CO与金属原子之间的相互作用机制。除铷和铯外，金属修饰后的显示出显著改善。结果表明，锂、钠、钾、钙、锶、钡和镧修饰的磷烯可用于消除CO或可逆储存CO。
