Tóm tắt

Exciton effects caused by the inherent dielectric confinement in the 2D material carbon nitride (CN) severely limit the transfer of photogenerated carriers and the selective generation of free radicals. Herein, a homo-hetero double junction coupling strategy is reported to address these challenges. Ternary homojunction carbon nitride (HCCN) functionalized with cyano and cyanamide groups is constructed with a built-in electric field that efficiently separates the electron-hole into different structural units, thereby reducing reverse charge recombination and weakening exciton effects.
