Correction: Surface reaction kinetics of the methanol synthesis and the water gas shift reaction on Cu/ZnO/Al$_{2}$O$_{3}$

A mistake was found in the Matlab program used for the simulations. That is, a parameter of the Gibbs free energy change of zinc reduction (ΔG$^{0}$$_{Zn}$ $_{red.}$) was wrongly typed, which participates in eqn (31) and (37) of the original paper. ΔG$^{0}$$_{Zn}$ $_{red.}$ is calculated from the thermodynamic data of Goos et al.,1 and the equation with the correct data is as follows.
ΔG$^{0}$$_{Zn}$ $_{red.}$= R·[8411.4 − 8.3237·T + 1.9335 × 10$^{-4}$·T$^{2}$ − 2.2728 × 10$^{-7}$·T$^{3}$−4.3047 × 10$^{-10}$·T$^{4}$ + 1.6777 × 10$^{-13}$·T$^{5}$ + 0.9824·T·ln(T)] (1)
With the corrected parameter, the zinc solubility in copper (X$_{Zn}$) and, consequently, the zinc coverage (ϕ$_{Zn}$) have lower values than the originally published ones, as shown in the revised Fig. 4.
