Abstract Photocatalytic conversion of waste carbon dioxide (CO 2 ) into fine chemicals is crucial for solar energy utilization and mitigating the global climate crisis. Artificial photocatalysis based on integrated biocatalyst offers a promising approach converting CO high‐value chemicals. The development metal‐free heterogeneous photocatalysts has gained significant attention as sustainable platform practical artificial photocatalytic systems. In this study, we report one‐pot synthesis covalent triazine‐based (CTPs) their applications. as‐synthesized CTPs exhibit excellent performance, achieving generation HCOOH from with yield 224.85 μM. underlying photo‐physical properties were investigated by using systematic time‐resolved laser spectroscopies. These measurements reveal that formation long‐lived charge transfer state in at late time window strongly correlated enhanced efficiency delaying ultrafast recombination. This study will serve benchmark example wide applications fixation chemical production.
