Abstract Poly(heptazine imide) (PHI) has received widely interest in the photocatalytic CO 2 reduction due to its good crystallinity and complete in‐plane structure. However, poor photo‐induced carrier separation migration efficiency insufficient active sites results undesirable performance. Herein, we designed constructed a novel ohmic junction photocatalyst by integrating melamine edge‐modified PHI (mel‐PHI) with extended π‐conjugated system TiN (TiN/mel‐PHI) for enhancing activity. Strikingly, yield of optimal TiN/mel‐PHI is 62.64 μmol g −1 h , which 5.6 2.8 times higher than (11.26 ) mel‐PHI (22.32 ), respectively. The superior activity attributed not only formation D‐A structure introduction melamine, extends π‐conjugation system, alters electronic PHI, accelerates charge migration, but also induced internal electric field further enhances efficiency. Meanwhile, synergistic effect enriched electron number TiN, reducing potential. This work highlights enhancement transfer between motifs junctions, confirming their potential optimizing photocatalysts.
