Key points
- A new alkali-assisted thermal polymerization strategy synthesizes nitrogen-deficient graphitic carbon nitride (g-C3Nx).
- Nitrogen vacancies introduced by alkali treatment redshift the absorption edge of g-C3Nx.
- Defect concentration is tunable by altering the alkali to nitrogen precursor ratio.
- g-C3Nx shows superior visible-light photocatalytic performance for hydrogen evolution compared to pristine g-C3N4.

Abstract
A facile synthetic strategy for nitrogen-deficient graphitic carbon nitride (g-C3Nx) is established, involving a simple alkali-assisted thermal polymerization of urea, melamine, or thiourea. In situ introduced nitrogen vacancies significantly redshift the absorption edge of g-C3Nx, with the defect concentration depending on the alkali to nitrogen precursor ratio. The g-C3Nx products show superior visible-light photocatalytic performance compared to pristine g-C3N4.
