Abstract Photocatalytic H 2 O production is a prospective alternative to the traditional anthraquinone oxidation method for production. Compared well‐established inorganic counterparts, organic photocatalysts show greater promise owing their structural diversity and functional tunability, but unfortunately suffer from limited activity at present. Here, comonomer doping strategy reported tune electronic structures of covalent triazine framework nanoshells by introducing strong electron‐withdrawing benzothiadiazole units into conjugated networks. The product exhibits much enhanced charge separation as evidenced multiple spectroscopic analyses. When investigated photocatalyst in aqueous solution, best sample can enable an impressive rate 1630 µmol g −1 h , which approximately three times higher than that undoped superior most other competitors.
