With time comes wisdom : Since the implementation of CuCl 2 for HCl oxidation by Deacon in 1868, the search for stable copper catalysts has been futile. Cuprous delafossite, CuCrO 2 (see picture), is shown to have unprecedented stability against chlorination, allowing for durable Cl 2 production with no metal loss. Based on this, a highly active CuCrO 2 ‐CeO 2 composite was developed, a cost‐effective Cl 2 recovery method.
