The methanol-to-olefins（MTO） reaction offers an alternative pathway for the production of low-carbon olefins from non-oil feedstocks. Fundamental research has been impeded by a lack of comprehensive understanding of its underlying mechanism,despite the signific.nt progress made in industry. In-situ solid-state nuclear magnetic resonance（ss nMR） spectroscopy has emerged as a pivotal tool, offering crucial insights into key species under real-time operando c.nditions. Furthermore, the host–guest interaction between zeolites or surface species residing on zeolites and the reactant/active intermediates is revealed by the combination of in-situ13c MAS nMR and 2D correlation spectroscopy. Moreover, rec.nt tec.nological advancements in hyperpolarization（HP） methods, including HP129Xe nMR and dynamic.nuclear polarization（DnP）, have signific.ntly improved the sensitivity of ss nMR, enabling detailed structural and kinetic analysis as well as the detection of trace species. In this feature article, we summarized rec.nt advancements in（in-situ） ss nMR spectroscopy applied to MTO reaction processes,encompassing mechanistic investigations at various stages and the intricate host–guest interactions. These theoretical insights into the dynamic evolution of MTO reactions lay a solid foundation for the optimization of catalytic processes and the development of efficient catalysts, thereby advanc.ng the tec.niques towards more sustainable and ec.nomical production route for olefins.

Zeolite nanosheets with a short b-axis thic.ness are highly desirable in lots of catalytic reactions due to their reduced diffusion resistance. nevertheless, c.nventional synthesis methods usually require expensive structure-directing agents(SDAs), pricey raw materials, and eco-unfriendly fluorine-c.ntaining additives. Here, we c.ntributed a cost-effective and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silicalite-1(Sil-1) seed suspension and urea cooperative strategy, only with inexpensive colloidal silica as the Si source. Our approach was effective for synthesizing both Sil-1 and aluminum-c.ntaining ZSM-5 nanosheets. By optimizing key synthesis parameters,including seed aging time, seed quantity, and urea c.nc.ntration, we achieved precise c.ntrol over the crystal face aspect ratio and b-axis thic.ness. We also revealed a non-classical oriented nanosheet growth mechanism, where Sil-1 seeds induced the formation of quasi-ordered precursor particles, and the(010)crystal planes of these particles facilitated urea adsorption, thereby promoting c-axis-oriented *** obtained ZSM-5 nanosheets exhibited exceptional catalytic performance in the benzene alkylation with ethanol, maintaining stability for over 500 h, which is 5 times longer than traditional ZSM-5 catalysts. Furthermore, large-scale production of ZSM-5 nanosheets was successfully carried out in a 3 L highpressure autoclave, yielding samples c.nsistent with those from laboratory-scale synthesis. This work marks a signific.nt step forward in the sustainable and efficient production of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applicability in catalysis.
