A Low-Temperature Solar Salt Approach to Fabricate Crystalline Polymeric Carbon Nitride for H₂O₂ Efficient Photosynthesis.

ABSTRACT: Photocatalytic technology based on polymeric carbon nitride (PCN) offers a sustainable and ecofriendly approach to hydrogen peroxide (H₂O₂) production field. Nonetheless, the effectiveness of PCN is significantly hindered by the strong binding energy of excitons and slow transfer ability of carriers. Herein, SS-UPCN-375 photocatalyst is prepared by one-pot solar salt (60% NaNO₃-40% KNO₃) thermal polymerization at 375 °C for the first time using nitrogen-rich precursors. The use of solar salt as a thermal reaction medium facilitates rapid control of the crystallization process and the electronic structure of photocatalysts, and yielding SS-UPCN-375 characterized by high crystallinity, augmented visible light utilization, and efficient exciton diss
