## 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.
