Resumo


Two-dimensional nanomaterials, such as graphene and phosphorene, has been attracting researchers’ interest, due to their possible applications. One of their applications is as gas sensors. Carbon dioxide is a gas, which needs to be monitored because it is one of the responsible for the greenhouse effect and for the changes in temperature. Therefore, the aim of this paper is to organize a literature review of the theoretical articles that use the Density Functional Theory to study graphene and phosphorene as carbon dioxide sensors. Analyzing the adsorption energies of the papers reviewed it is concluded that graphene and phosphorene are more promising sensors for carbon dioxide when this molecule is adsorbed on the graphene edged or when it is adsorbed on doped phosphorene. This literature review opens new perspectives for experimental studies.
