ABSTRACT

In summary, the dynamic migration of indium plays a pivotal role in the formation of stable single-atom RhIn cluster catalysts within zeolite matrix. The unique RhIn@S-1 catalyst discovered by Wang and coworkers effectively prevents metal sintering, which is a great challenge in the field of heterogeneous catalysis. The newly-developed Rh-based catalyst beyond Pt- and Cr-based catalysts ensures an unprecedented lifetime of alkane dehydrogenation. Compared to current commercial catalysts, the lifespan of catalysts has increased by 1-2 orders of magnitude, avoiding the frequent regeneration and complex operating procedures, holding immense potential for future large-scale applications. Furthermore, the mechanistic findings represent a significant leap forward in catalysis and lay a solid foundation for the deliberate design of efficient and durable catalysts for various catalytic processes.
