The efficient conversion of CO₂ to chemical fuels driven by solar energy is still a challenging research area in photosynthesis, in which the conversion efficiency greatly relies on photocatalytic coenzyme NADH regeneration. Herein, a photocatalyst/biocatalyst synergetic system based on a conjugated microporous polymer (CMP) was prepared for sustainable and highly selective photocatalytic reduction of CO₂ to methanol. Two thiazolo[5,4-d]thiazole-linked CMPs (TZTZ-TA and TZTZ-TP) were designed and synthesized as photocatalysts. Slight skeleton modification led to a great difference in their photocatalytic performance. Triazine-based TZTZ-TA exhibited an unprecedentedly high NADH regeneration efficiency of 82.0% yield within 5 min. Furthermore, the in situ photocatalytic NADH regeneration system could integrate with three consecutive enzymes for efficient conversion of CO₂ into methanol. This CMP–enzyme hybrid system provides a new avenue for accomplishing the liquid sunshine from CO₂.

基于噻唑并[5,4-d]噻唑的二维网络的构建，以有效地光催化还原CO2。

在光合作用中，将CO ₂有效转化为太阳能驱动的化学燃料仍然是一个充满挑战的研究领域，其中转化效率在很大程度上取决于光催化辅酶NADH的再生。在此，制备了基于共轭微孔聚合物（CMP）的光催化剂/生物催化剂协同系统，用于将CO ₂可持续且高度选择性地光催化还原为甲醇。设计并合成了两种噻唑并[5,4 - d ]噻唑连接的CMP（TZTZ-TA和TZTZ-TP）作为光催化剂。轻微的骨架修饰导致其光催化性能的巨大差异。三嗪基TZTZ-TA在5分钟内显示出前所未有的高NADH再生效率，收率为82.0％。此外，原位光催化NADH再生系统可以与三个连续的酶整合，以有效地将CO ₂转化为甲醇。这种CMP-酶混合系统为从CO _2中获得液态阳光提供了新途径。
