Abstract
We numerically study the effect of a particular kind of non-Gaussian colored noise (NGN) on the intrinsic stochastic reaction rate oscillations (RRO) in NO reduction with CO on small-size Pt surfaces. It was found that the RRO can be enhanced by the appropriate noise strength, correlation time, in particular, the deviation of the NGN from Gaussian noise. Furthermore, there is an optimal NGN by which the RRO can be most greatly enhanced. This result shows that the RRO can be enhanced by different types of the NGN, and can reach the best oscillatory state by utilizing one optimal type of the noise. A simple explanation for the phenomenon is given.
