Efficiently improving photocatalytic efficiency of carbon nitride (g-C3N4), a pro-mising candidate, for H-2 production is of great significance but remains a challenge. Herein, a unique N-deficient g-C3N4 homojunction (I/R-CN) prepared by an inserting-removing strategy via thermal polymerization of a freeze-dried mixture containing dicyandiamide, NH4Cl, and a prepolymer from 3-amino-1,2,4-triazol (3-AT) is reported, in which the prepolymerization process of 3-AT under optimized conditions is indispensible. I/R-CN features the N-deficient gC(3)N(4) microdomains (NDMD) from prepolymer inserting into a porous N-defects modified g-C3N4 with two kinds of N defects (N vacancies and cyano groups) formed by removing N atoms from the skeleton of g-C3N4, unambiguously confirmed by various characterizations. I/R-CN exhibits notably promoted photocatalysis with a high H-2 evolution rate of 3882.5 mu mol h(-1) g(-1) and a large apparent quantum yield of 8.6 % at 420 nm, originating from the efficient recombination inhibition of electron-hole pairs by the markedly promoted charge mobility as well as the improved light absorption capacity and enlarged reduction potential. This work paves a new avenue for designing other highly-efficient carbon nitride photocatalysts for solar applications.
