In situ electrocatalytic conversion of low-concentration carbon dioxide (CO) from anaerobic fermentation gas (AFG) into high-value chemical products can effectively mitigate the costs associated with carbon capture, enrichment, and transfer. In this study, we synthesized a guanidine-based porous organic polymer (G-POPs-1), which efficiently enriches and activates diluted CO to form a "carbon-pool". Subsequently, through indirect electromediated oxidation, the 4-pentenamine substrate underwent sequential cyclical reactions to produce proline carbamate. Moreover, after six cycles of use, G-POPs-1 exhibited minimal degradation in catalytic performance, with its microstructure remaining intact.
将厌氧发酵气（AFG）中的低浓度二氧化碳（CO）原位电催化转化为高价值化学产品，可有效降低与碳捕获、富集和转移相关的成本。在本研究中，我们合成了一种胍基多孔有机聚合物（G-POPs-1），它能有效富集和活化稀释的CO，形成“碳池”。随后，通过间接电介导氧化，4-戊烯胺底物进行连续循环反应生成脯氨酸氨基甲酸酯。此外，在使用六个循环后，G-POPs-1的催化性能降解极小，其微观结构保持完整。
