[Pw_forum] Binding energy of Ti on Graphene oxide sheet

[rajiv kumar]

I was going through the paper "wang et. al. ACS nano Vol3, No.10,
2995-3000, (2009)" where the binding energy of Titanium on Graphene oxide
(figure:3) was done using below mentioned formula:
Eb (Ti) = E(GO) + E(Ti) - E(Ti/GO)

Here I have a confusion, as for E(GO) some of the oxygen atoms are double
bonded with the Graphene sheet, but in E(Ti/GO) few oxygen breaks one of
the bond from the sheet and get attached to Ti atom. So here the final
structure of Ti-with-GO is completely different. So my question is that is
the way of calculating the Binding energy of Ti on Grapehene oxide is
correct?  If yes then can anyone explain this?
