CO2 as a greenhouse gas causes a series of issues, and catalytic utilization of CO2 to fuels is a favorable strategy. Herein, we report the discovery in CO2 hydrogenation reaction where C5+ yield can be evidently improved by encapsulating ZnFe2O4 inside ZSM‐5, in which the micro‐environments of core‐shell components can be tuned. For the ZnFe2O4, the K promoter makes the FeC structure more electron deficient than the Na, which contributes to the formation of long‐chain olefins. ZSM‐5 with K or Ce modification presents enhanced adsorption ability of alkene, then promoting aromatization and isomerization reactions of alkenes. Compared with Ce, K‐ZSM‐5 contributes to isomerization rather than aromatization, forming more isoparaffins. In this work, regulating the microenvironment of capsule catalysts provides a new idea for the design of efficient tandem catalysts, and expands the ability of hybrid catalysts against other catalysts, thus presenting an excellent catalytic efficiency for CO2 upgrading.

具有可调节微环境的空间受限胶囊催化剂，可实现高效的二氧化碳转化

一氧化碳2作为一种温室气体会引起一系列问题，而CO的催化利用2转向燃料是一个有利的策略。在此，我们报告了 CO 中的发现2加氢反应，其中C5+封装ZnFe可以明显提高成品率2氧4在 ZSM-5 内部，可以调节核壳组件的微环境。对于铁锌2氧4，K促进剂使FeC结构比Na更缺电子，这有助于长链烯烃的形成。 K或Ce修饰的ZSM-5增强了烯烃的吸附能力，进而促进烯烃的芳构化和异构化反应。与Ce相比，K-ZSM-5有助于异构化而不是芳构化，形成更多的异构烷烃。在这项工作中，调控胶囊催化剂的微环境为高效串联催化剂的设计提供了新的思路，并扩展了混合催化剂相对于其他催化剂的能力，从而呈现出优异的CO催化效率2升级。
