摘要

由于甲醇制烯烃 (MTO) 转化的复杂性，阐明失活机理仍是一项挑战。在本期《化学催化》（Chem Catalysis）杂志上，范伟斌及其合作者阐明了焦炭前体（即交联共轭物）在沸石催化剂上的形成和演化，为 MTO 转化过程中的失活机理提供了新的见解。

Unraveling the deactivation mechanism of methanol-to-olefin conversion over zeolite catalysts

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.
