The stability conditions for mathematical models of carbon monoxide oxidation on the surface of gold nanoparticles are investigated.  The cases of reaction mechanisms of one-step and step-by-step transformation of reagents are consecutively considered.  Using the stability analysis by Lyapunov method, it is shown that models which take into account the possibility of structural changes of the catalyst surface can predict the occurrence of oscillatory mode in the system as a result of Hopf instability.
