近日，北京航空航天大學(xué)梁潔團(tuán)隊(duì)報(bào)道了一種用于生物質(zhì)催化熱解的漏斗結(jié)構(gòu)12×10環(huán)沸石。相關(guān)論文于2025年12月16日發(fā)表在《美國(guó)化學(xué)會(huì)志》上。 基于預(yù)置反應(yīng)需求的"按需定制式"沸石合成對(duì)沸石工程至關(guān)重要。催化快速熱解技術(shù)作為將生物質(zhì)直接轉(zhuǎn)化為即用型烴類燃料的前沿路徑，亟需具有梯度大/中孔結(jié)構(gòu)的沸石催化劑，但此類預(yù)設(shè)結(jié)構(gòu)沸石的合成仍面臨挑戰(zhàn)。 研究組提出一種原位部分沸石轉(zhuǎn)化策略，成功制備了專為生物質(zhì)催化快速熱解設(shè)計(jì)的核殼結(jié)構(gòu)HS-ZSM-5@Beta異質(zhì)沸石。原子級(jí)集成微分相位襯度掃描透射電子顯微鏡表征顯示，該材料具有無縫銜接的核殼界面及漏斗狀12×10元環(huán)通道結(jié)構(gòu)。憑借其明確的"核到殼"傳質(zhì)路徑與增強(qiáng)的孔道協(xié)同效應(yīng)，HS-ZSM-5@Beta在玉米秸稈催化快速熱解中實(shí)現(xiàn)了57.4%的烴類產(chǎn)物選擇性，是傳統(tǒng)ZSM-5催化劑的兩倍，且在八次熱解-再生循環(huán)后仍保持穩(wěn)定的催化活性。結(jié)構(gòu)-性能關(guān)系研究揭示了該合成策略的動(dòng)力學(xué)優(yōu)勢(shì)。該工作為面向預(yù)設(shè)反應(yīng)的沸石理性設(shè)計(jì)提供了重要突破。 附：英文原文 Title: A Funnel-Structured 12 × 10-Ring Zeolite Customized for Biomass Catalytic Pyrolysis Author: Liu Wu, Xiaoge Wang, Shihao Wang, Jing Ju, Zhentao Chen, Junliang Sun, Jie Liang Issue&Volume: December 16, 2025 Abstract: “Ab initio” synthesis of reaction-customized zeolites is essential for zeolite engineering. Catalytic fast pyrolysis (CFP) represents a promising reaction to directly convert biomass into drop-in hydrocarbon fuels, which necessitates zeolites with a gradient large-/medium-porosity. However, the synthesis of such a predefined zeolite is challenging. Herein, an in situ partial interzeolite transformation strategy is proposed to fabricate a core–shell HS-ZSM-5@Beta heterozeolite tailored for biomass CFP. HS-ZSM-5@Beta features a seamless core-to-shell interface and funnel-structured 12 × 10-membered ring (MR) channels, as revealed by atomic-level integrated differential phase contrast scanning transmission electron microscopy (iDPC-STEM). With the well-defined “core-to-shell” pathway and enhanced porosity synergy, HS-ZSM-5@Beta delivers a hydrocarbon selectivity of 57.4 area % during maize straw CFP, which is twice that of conventional ZSM-5. The robust catalytic activity is retained over eight pyrolysis-regeneration cycles. A structure–property relationship investigation underscores the kinetic advantages of this synthetic approach. This study advances the real rational design of zeolites for pre-established reactions. DOI: 10.1021/jacs.5c17648 Source: https://pubs.acs.org/doi/abs/10.1021/jacs.5c17648
