“…Some studies have been performed to explain the mechanism of visible photoluminescence (PL) of carbon nitride. The photoluminescence area is dominated by the optical band gap and it was indicated that the band gap of g-C 3 N 4 is tunable with processing temperature [44,45]. Zhang et al [46] have studied the photoluminescence tune-ability of synthesized g-C 3 N 4 nanopowder.…”

The g-C3N4 which is well known as a polymeric non-metal semiconductor, has been fabricated by thermal polymerization. It has also been used in catalytic applications including, photo-catalysis, removal and degradation of pollutants in water, Friedel-Crafts reactions, oxygen reduction reaction and etc. It has drawn noticeable research attention due to its economical and affordable fabrication, non-toxicity, biocompatibility, good thermal and electrical conductivity, high hardness, Corrosion resistance, and fireproofing properties. Therefore, the g-C3N4 has found non-catalytic applications including composites, cutting tools, improving surface properties, light emitting devices, optical sensors, and solar cells. In the current review, the novel and non-catalytic applications of g-C3N4 have been highlighted.

“…[31][32][33][34] Based on the above problems, a lot of methods have been employed to improve the photocatalytic performance, including defect construction, heteroatom doping, morphology optimization, etc. [35][36][37][38][39][40] For example, the photocatalytic H 2 O 2 generation activity was signicantly enhanced by constructing carbon vacancies 18 or nitrogen vacancies 19 on the surface of g-C 3 N 4 due to the improved light harvesting capacity. Heteroatom doping, for example, Fe and non-metal S, P doping, has been proved to be an effective approach to boost the photocatalytic hydrogen generation activity and pollutants degradation.…”

Graphitic carbon nitride (g-C3N4) is gaining more and more attentions as a promising metal-free photocatalyst for H2 production. Nevertheless, from the perspective of practical applications, the photocatalytic performance over g-C3N4 in visible-light region needs a further improvment. In this work, C doping and C quantum dots (QDs) are co-integrated in g-C3N4 by a one-step thermal polymerization method to obtain an advanced C QDs/C doped g-C3N4 photocatalyst. The synergistic effects of C doping and C QDs modification promote the photocatalytic activity of g-C3N4 significantly. The optimal C QDs/C doped g-C3N4 exhibits a significant improvement on visible-light-driven photocatalytic hydrogen production (509 μmol g-1 h-1) with an apparent quantum yield (AQE) at 420 nm reaching 1.24%, which is approximately 9-fold enhancement than that of pristine g-C3N4. The increased photocatalytic activity mainly benefits from the enhanced visible light absorption and carrier separation efficiency. This study may open a new perspective for the design and fabrication of C-modified g-C3N4 for photocatalytic hydrogen production.
