  The Koper model is a vector field in which the differential equations
describe the electrochemical oscillations appearing in diffusion processes.
This work focuses on the understanding of the slow dynamics of stochastic Koper
model perturbed by stable L\'evy noise. We establish the slow manifold for
stochastic Koper model with stable L\'evy noise and verify exponential tracking
property. We also present a practical example to demonstrate the analytical
results with numerical simulations.
