Abstract Polymeric g‐C 3 N 4 is a promising visible‐light‐responsive photocatalyst; however, the fast recombination of charge carriers and moderate oxidation ability remarkably restrict its photocatalytic efficiency towards organic pollutants. To overcome these drawbacks, self‐modification strategy one‐step formaldehyde‐assisted thermal polycondensation molten urea to prepare carbon‐deficient oxygen‐doped (V C ‐OCN) developed, carbon vacancy concentration well‐controlled by changing formaldehyde dosage. The V ‐OCN catalysts exhibit interesting concentration‐dependent removal p ‐nitrophenol (PNP) atrazine (ATN), in which 15 with appropriate displays significantly higher pollutant than bulk . apparent first‐order rate constant for PNP ATN 4.4 5.2 times that A combination experimental results theoretic calculations confirm synergetic effect vacancies oxygen doping sites can not only delay but also facilitate adsorption molecules on vacancies, leads generation plentiful active species including superoxide anion radicals indirectly formed hydroxyl singlet oxygen.
