I am not sure what you mean, but here's an example of adsorbing a benzene molecule om the Au(111) surface: http://docs.quantumwise.com/tutorials/benzene_au111/benzene_au111.html

How we can adsorb the phosphorous molecule over graphene sheet  ?

[Jess Wellendorff]

Very similar to the tutorial:
1) build graphene
2) build phosphorous molecule (or find it in the Molecular Builder if it is there)
3) combine the two in the desired geometry.
