- Electroenzymatic CO 2 Reduction Through Hollow Covalent Organic Framework‐Immobilized Enzyme With Neutral Red‐Modified Electrode Hengrui Zuo Luting Wang Yaoxuan Li Tiantian Wang Liya Zhou Xiaobing Zheng Yunting Liu Guanhua Liu Yanjun Jiang ChemSusChem To meet the global pursuit of carbon neutrality, electroenzymatic reduction of CO 2 has been a potential technology that can convert CO 2 into useful chemicals or fuels. However, the low solubility of CO 2 in water inhibits the reaction rate, and free enzyme suffers from poor stability and reusability and requires the expensive cofactor NADH. Herein, a spherical covalent organic framework (COF) TPB‐DMTP was synthesized for both CO 2 enrichment and enzyme immobilization. The electron mediator neutral red was covalently attached to a carbon paper electrode for electrochemical NADH regeneration, thereby avoiding damage to the enzyme. The constructed electrocatalytic NADH regeneration was coupled with enzyme‐catalyzed CO 2 reduction. After immobilizing formate dehydrogenase (FDH) in the COF, the CO 2 was enriched near the enzyme molecules, and the stability and reusability of enzyme were enhanced. The optimized system produced up to 2.312 mM formate, which was 4.01 times that of the free enzyme system. 10.1002/cssc.70761 http://onlinelibrary.wiley.com/termsAndConditions#vor
