Reactivity of Surface Hydroxyl Groups with Metal Complex Compounds

Abstract

The surface reaction of the adsorbed hydroxyl group OH(a) with $$Rh{\left( {CO} \right)_2}\left( {\pi - {C_3}{H_5}} \right)$$ delivered from the gas phase:$$OH\left( a \right) + Rh{\left( {CO} \right)_2}\left( {\pi - {C_3}{H_5}} \right)\left( g \right) \to O - Rh{\left( {CO} \right)_2}\left( a \right) + {C_3}{H_6}\left( {a/g} \right)$$ has been studied on Ni(110), Ni(100) and ZnO($$10\bar 10$$) mainly by HREELS and TPRS. On Ni(110), p(2 × 1)-OH(a) was completely diminished by adsorption of $$Rh{\left( {CO} \right)_2}\left( {\pi - {C_3}{H_5}} \right)$$ below 300 K. C3H6 stayed on the surface after this reaction. On ZnO($$10\bar 10$$) OH(a) was deposited with surface defects introduced by Ar ion bombardment. The sane reaction occurred with OH(a) on ZnO($$10\bar 10$$), but not completely on Ni(100) which was covered with oxide layers.KeywordsLEED PatternMetal Complex CompoundHREEL SpectrumVariable Leak ValveDark Yellow pOWderThese keywords were added by machine and not by the authors.
