Enhancement of stochastic reaction rate oscillations by external noise in CO oxidation on nanometer-sized Pd particles

With increasing noise intensity, the SNR maximum increases and reaches a largest value, and then decreases, till lower than the SNR maximum for D = 0, representing the reaction rate oscillations can be enhanced by external noise and, furthermore, can be most highly enhanced by optimal external noise. This implies the reaction rate oscillations can selectively exploit the external noise to reach a best oscillatory performance.
