We performed the quantum chemical calculation to study (1)
the adsorption of chosen molecules not only to represent various
industrially important hydrocarbons and heterocyclic compounds,
but also because they are known to be common failures
for conventional DFT calculations: unsaturated aliphatic
(ethene), aromatics (benzene and ethylbenzene), and heterocycles
(pyridine) and (2) the hydrogen exchange reaction of aromatics
(benzene and ethylbenzene). The hydrogen exchange is chosen
because of its simplicity; it consists of a single concerted step, and
