Summary: Noncatalytic gas-solid reactions are commonly assumed to be irreversible, but this study shows the existence of reverse elements in the Ni oxidation reaction, resulting in NiO reduction. The oxidation process involves preferential CO2 adsorption along step edges, while the reduction process involves preferential CO adsorption on step edges. Temperature and CO2 pressure effect maps are constructed to illustrate the dynamics of the competing NiO redox reactions. This study demonstrates the ability to manipulate gas-solid reactions by controlling the gas environment or atomic structure of the solid surface.
