Kinetic oscillation of carbon monoxide oxidation over nano-scaled catalyst involving temperature variation

Monte Carlo technique was applied to simulate the temperature variation caused by local overheating and its influence on kinetic oscillation of carbon monoxide oxidation over nano-scaled catalysts. Contracted oscillatory period was observed due to the nonisothermal effect on the rate constants. The temperature window for oscillation was shifted downward from our simulation comparing to that predicted by isothermal simulation. The increasing size of catalyst was found to enhance the extent of temperature variation and result in shorter oscillation period.
