Microkinetic modeling is a powerful technique used to analyze complex catalytic networks in terms of elementary reactions. Herein, no assumptions are made, a priori, about the rate-determining steps or surface coverage of intermediate species. In this fashion, measured or calculated parameters such as activation and reaction free energies can be incorporated into the rate expressions. Regarding the reactor model, a continuous stirred-tank reactor (CSTR) was chosen to solve the rate equations. In this way, the time evolution of the coverages and pressures of each species can be obtained. The details of the reaction network are given in the Supporting Information. The simulations were run for at least 10 7 s to ensure convergence to a dynamic steady-state. An important point should be made here mentioning that the achieved dynamic steady-state differs significantly from the thermodynamic equilibrium as there is a continuous gas inlet and outlet which brings the system out of equilibrium in a dynamic way. The total flow rate was set to 8 ml min -1 with different O 2 :CO compositions. 100 mg of catalyst was used with a Pt loading of 0.35 wt%. Pt and Ge sites were treated equivalently in the spirit of the mean-field approach.
