Because of the complexity of methanol-to-olefin (MTO) conversion, clarifying the deactivation mechanism is still challenging. In this issue of Chem Catalysis, Weibin Fan and co-workers clarify the formation and evolution of coke precursors, i.e., cross-linked conjugate species, over zeolite catalysts, providing new insights into the deactivation mechanism in MTO conversion.

揭示沸石催化剂上甲醇转化为烯烃的失活机理

由于甲醇转化为烯烃（MTO）的复杂性，阐明失活机制仍然具有挑战性。在本期《化学催化》中，范伟斌及其同事阐明了焦炭前体（即交联共轭物）在沸石催化剂上的形成和演化，为 MTO 转化中的失活机制提供了新的见解。
