On the other hand, it is well known that phosphorene is prone to oxidize when it is exposed to air and water, which changes its structure and properties depending on the type of the formed oxide [PxOy or PxOy(OH)z] . A computational study explored many possible reaction products between phosphorene and oxygen, resulting in the most stable species in contact with water, the PxO type suboxides (with x=8, 6, 4, 2) . This partial oxidation type of phosphorene surface is another interesting property to explore the adsorption ability of this material, which could show an improved adsorption capacity compared to its pristine counterpart like graphene oxide . The latter turns into a key point because the oxidized forms could be the reliable structures to act as adsorbents in pollutant removal. With this in mind, a surface structure with dangling oxygen atoms (P-O) is the most stable configuration of oxidized phosphorene for low/medium oxygen concentrations (Scheme 1f) . In addition, an easy bottom-up synthesis route for partially oxidized phosphorene surfaces can be addressed . In this way, the properties of pristine phosphorene could be preserved in the oxidized forms, with slight changes in the structure of oxidized phosphorene confirming the primary role of oxygen on the surface and their beneficial application in an aqueous environment .
