Abstract Many cases of light absorption modification exceeding 700 nm or near‐infrared (NIR) are reported for capturing more than half the solar energy, however, very few modifications can produce NIR photoactivity due to inevitably introduced defects‐induced non‐radiative recombination. Here, taking four kinds C/O co‐doped red polymeric carbon nitride as examples, defect‐repairing is carried out using alkali metal molten‐salts (LiCl/NaCl and LiCl/KCl) solid‐salt (KCl) activate their photoactivity. The defect repair results from passivation valence electron pairing formation crystalline polyheptazine imide structure with complete polymerization. More importantly, it sharply eliminates bulk defects (such vacancy nitrogen vacancy) by co‐doping. Since structural in most photocatalysts during expanding absorption, this proposed strategy bound be universal suppressing recombination

Abstract Carbon nitrides with two‐dimensional layered structures and high theoretical capacities are attractive as anode materials for sodium‐ion batteries while their low crystallinity insufficient structural stability strongly restrict practical applications. Coupling carbon conductive may relieve these issues. However, little is known about the influence of nitrogen (N) configurations on interactions between C 3 N 4 , which fundamentally critical guiding precise design advanced ‐related electrodes. Herein, highly crystalline (poly (triazine imide), PTI) based all‐carbon composites were developed by molten salt strategy. More importantly, vital role pyrrolic‐N enhancing charge transfer boosting Na + storage ‐based composites, was confirmed both experimental evidence, spot‐highlighted first time. By elaborately controlling composition, composite minimized graphitic‐N content obtained. Profiting from formation PTI electrochemically favorable configurations, delivered an unusual reverse growth record‐level cycling even after 5000 cycles along reversible capacity outstanding full‐cell retention. This work broadens energy applications provides new prospects
