The interaction between Pt, and ideal or O-defective (110) rutile surfaces, was studied by using  ab initio  methods. The results revealed that the interaction between Pt and TiO2 was very strong, with the bond energy reaching 16.5eV for the ideal surface and 23.0eV for the O-defective surface. It appeared that Pt was preferentially adsorbed at the O vacant site on the (110) surface.
