Abstract Changes with time in the isotopic exchange reaction rate between H2, and HDO(v) over a hydrophobic Pt-catalyst induced by the addition of HNO3 were studied experimentally. The HNO3 poisoning was found to be reversible and was well explained in terms of the competitive adsorption of HNO3 with H2 or HDO onto the catalytic active sites. The adsorption equilibrium for HNO3 could be expressed by the Frumkin-Temkin equation and the time evolution of the activity was well expressed by the Zeldovich rate equation.
