A proposal for the self-healing nature of Pt–Pd catalysts is shown in Figure 9. The PdO traps mobile PtO 2, and as the concentration of Pt builds up, it can transform the oxide into a metal phase. This we feel is the origin of Pt–Pd on one face of the particle, coexisting with PdO.

Suppose ϵ ≪ 1 is small and t is larger. Then. Cov ( B ϵ, B t) = ϵ, Cov ( B t + ϵ, B 2 t) = t + ϵ. In both cases the time step is t − ϵ, but the covariances are ...
