Abstract

We report a novel reversible color switching system based on one-pot hydrogenation/oxygenation reactions over Pd/CeO_2-x catalysts and fast interconversion of thionine (TH⁺) and leuco thionine (LTH). Oxygen vacancies produced by Pd-catalyzed instant hydrogenation of CeO₂ and strong metal-support interaction (SMSI) could lead to fast color switching.
