As the crystalline phase of g-C3N4, poly(heptazine imide) (PHI) is attracting increasing attention recently due to its advantages in light absorption and charge transfer compared with the commonly studied g-C3N4 with Melon structure. Crystallinity engineering to further enhance its crystallinity may significantly improve the photocatalytic performances and thus the effective strategy is highly desirable. Herein, we propose a post-thermal treatment assisted ionothermal protocol to achieve the crystallinity elevation of PHI. By simply adding an extra annealing step in thermal polycondensation of precursors to tune Melon structure, the recondensation process for PHI synthesis was directly modified, leading to the formation of high-crystalline product. The synthesized materials therefore presented decreased interlayer stacking distance, narrowed bandgap and improved charge transfer/separation kinetics, which remarkably enhanced the visible-light photocatalytic activities of PHI. This work provides references for structural modifications of high-crystalline g-C3N4 based materials, which may inspire new ideas for the design of high-performance photocatalysts. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Related Products of 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Related Products of 7447-41-8
