Selective substitution : In the oxidation of HCl with oxygen to give Cl 2 and water, RuO 2 (110) serves as a stable, active model catalyst for the Sumitomo process (see picture; Ru in red and blue). The stability of the catalyst is related to the selective replacement of undercoordinated bridging surface O atoms (O br ) by Cl atoms (Cl br ). The chlorination of RuO 2 (110) is self‐limiting, in that chlorine incorporation terminates when all bridging O atoms are replaced.
