title: Highly efficient redox-driven reversible color switching of dye molecules via hydrogenation/oxygenation.
abstract: We report a novel reversible color switching system based on one-pot hydrogenation/oxygenation reactions over Pd/CeO2-xcatalysts and fast interconversion of thionine (TH+) and leuco thionine (LTH). Oxygen vacancies produced by Pd-catalyzed instant hydrogenation of CeO2and strong metal-support interaction (SMSI) could lead to fast color switching.
