The authors regret that the incorrect values were given in Table 3 for the activation energy and the rate constant at 350 °C for k_2,Pe,Ps due to a copy/paste error. Instead of 49.7 kJ mol⁻¹ and 1.02 min⁻¹, as shown in the table, the values should be 57.5 kJ mol⁻¹ and 0.226 min⁻¹. These corrections do not alter any of the figures or discussion in the manuscript and the conclusions remain unchanged as well. The authors apologize for this error and any difficulty it may have caused for interested readers.

The correct Table 3 reads as follow:
