Poly(heptazine imide) (PHI) has received widely interest in the photocatalytic CO2 reduction due to its good crystallinity and complete in‐plane structure. However, its poor photo‐induced carrier separation and migration efficiency and insufficient active sites results in undesirable photocatalytic CO2 reduction performance. Herein, we designed and constructed a novel ohmic junction photocatalyst by integrating melamine edge‐modified PHI (mel‐PHI) with extended π‐conjugated system with TiN (TiN/mel‐PHI) for enhancing the photocatalytic CO2 reduction activity. Strikingly, the photocayalytic CO2 reduction yield of the optimal TiN/mel‐PHI is 62.64 µmol·g–1·h–1, which is 5.6 and 2.8 times higher than PHI (11.26 µmol·g–1·h–1) and mel‐PHI (22.32 µmol·g–1·h–1), respectively. The superior photocatalytic CO2 reduction activity is attributed not only to the formation of D‐A structure by the introduction of melamine, which extends the π‐conjugation system, alters the electronic structure of PHI, and accelerates the charge separation and migration, but also to the induced internal electric field by ohmic junction further enhances the charge separation and migration efficiency. Meanwhile, the synergistic effect of mel‐PHI and TiN enriched the electron number of TiN, reducing the CO2 reduction potential. This work highlights the synergistic enhancement of charge transfer between D‐A motifs and ohmic junctions, confirming their potential in optimizing photocatalysts.

As dye wastewater poses increasingly significant harm to the natural environment, the development of visible light responsive catalysts for the efficient degradation of dyes has become imperative. In this work, Zn0.6Cd0.4S solid solution modified Bi2MoO6 was synthesized via a two‐step solvothermal method. The photocatalytic performance of the catalyst was evaluated through the degradation of Rhodamine B (RhB) under visible light irradiation. The results indicated that the 10 wt% Zn0.6Cd0.4S/Bi2MoO6 (10% ZCS/BMO) composite exhibited remarkable RhB removal efficiency, achieving 92.8% after 2.5 h, while pristine BMO demonstrated only 53.6% removal. This enhancement was attributed to the successful construction of a heterojunction in the 10% ZCS/BMO composite, which led to low fluorescence intensity, signifying efficient separation of photogenerated carriers. Consequently, the photocatalytic activity of BMO was substantially improved. Furthermore, ·O2− played a pivotal role in RhB degradation. This work provides a reference for the design of efficient visible‐light‐driven catalyst, facilitating the rapid purification of dye wastewater.
