Dynamic structural changes in the reactive environment often lead to catalyst deactivation thermal-catalysis field. Taking advantage of dynamic bulk phases, interfaces, and surface structures design highly active catalysts is a unique but important strategy. Herein, we report supersaturated ceria solid solution enabling styrene yield 91.8% over extended redox cycles at 430 °C oxidative dehydrogenation (ODH) ethylbenzene. In-situ characterizations reveal that oxygen anions (O2–) transition-metal cations (Fe Mn) reversibly shuttle through (bulk ↔ surface) K–Ce0.47Fe0.2Mn0.33O2−δ during ODH process. The acts as cations/oxygen reservoir, creating atomic interfaces K–Fe–O/K–Mn–O an gateway for efficient ethylbenzene ODH. findings concerning formation cations, lattice migration, coupling between donation catalytic reactions offer new strategies designing high-performance catalysts.

Extensive research efforts have been devoted to using greenhouse gas CO2 in upgrading bio-derived feedstock value-added chemicals the oxidative dehydrogenation route (CO2-ODH) with low-energy input. To realize effective deployment of CO2-ODH at an industrial scale, it is imperative advance development robust catalysts that can selectively catalyze C-H over C-C bonds, while simultaneously demonstrating thermodynamic stability coke formation or sintering. Transition metal-based exhibit significant potential for being highly selective and reactive simultaneous conversion hydrocarbons, owing their surface reducibility, well-balanced acid/base properties, dynamic oxygen storage capacity. stimulate further optimization, it's crucial discover key design principles, trends descriptors, strategies fine-tune catalyst materials. This review comprehensively examines experimental theoretical aimed pinpointing catalytic characteristics affect selectivity transition mono, bi, multimetal oxides. It covers aspects like combinations active metals supports, effects composition alloying, interfacial structures, adsorption strengths, dynamics in-situ restructuring, defect creation, morphology, electronic among others. We wrap up by suggesting approaches overcome present obstacles reactor technology, potentially bridging lab-to-industry gap this domain.
