Different synthesis temperatures (450–550 °C) were applied to synthesize g-C3N4 with the highest visible-light triggered photocatalytic activity. The best performing photocatalyst was synthesized at 550 °C due created favourable structure that expressed lowest band gap and charge carrier recombination rate. To further improve activity of g-C3N4, different g-C3N4/TiO2 (gCN/TNP) composites varyin...

A g-C3N4/nanocarbon/ZnIn2S4 (CN/C/ZIS) nanocomposite with enhanced photocatalytic H2 production performance has been successfully synthesized. Based on the experimental results, for the first time, it has been demonstrated that nanocarbon could be integrated into a Z-scheme photocatalytic system and acted as an excellent solid electron mediator.

Two-dimensional g-C3N4 nanosheets with few-layer thickness, ensuring equivalent charge migrations to various Pd facets, provide an ideal model system for reliably examining the facet selectivity of Pd co-catalysts. It reveals that reduction of CO2 can occur better on Pd{111} facets while H2O prefers to generate H2 on Pd{100}.

NIR light induced H2 evolution was realized by metal-free photocatalysis for the first time. The considerable H2 production at 808 nm and large promotion of the photocatalytic activity in both UV-Vis and Vis regions originated from the synergistic effect on spectral and electronic coupling of g-C3N4 nanosheets and carbon quantum dots.

The design and construction of heterojunction photocatalysts, which possess a staggered energy band structure appropriate interfacial contact, is an effective way to achieve outstanding photocatalytic performance. In this study, 2D/2D BiOBr/g-C3N4 heterojunctions were successfully obtained by convenient in situ self-assembly route. Under simulated sunlight irradiation, 99% RhB (10 mg·L−1, 100 m...

According to experimental measurements first-principle calculations, the formation built-in electric field opposite band bending around interface region in as well intimate contact between 2D will lead high separation efficiency charg...

In this work, we report a W single atoms modified g-C3N4 porous unltrathin nanosheets (WSA-CN-PUNS) catalyst for photocatalytic H2 evolution, which is synthesized by simply calcining the polyprrole-polyoxometalate/g-C3N4 composite in air. DFT calculation and experimental results reveal that WSA-CN-PUNS has reduced band-gap, dopant-related defect levels inhibited charge recombination. As result,...

Expanding the optical absorption range of photocatalysts is still a key endeavor in graphitic carbon nitride (g-C3N4) studies. Here, we report on novel thiophene group extending property, which assigned to n-π* electronic transitions involving two lone pairs sulfur (TLPS). The as-prepared samples, denoted as CN-ThAx (where x indicates amount ThA added, mg), showed an additional above 500 nm com...

Durable and inexpensive graphitic carbon nitride (g-C3N4) demonstrates great potential for achieving efficient photocatalytic hydrogen evolution reduction (HER). To further improve its activity, g-C3N4 was subjected to atomic-level structural engineering by doping with transition metals (M = Fe, Co, or Ni), which simultaneously induced the formation of metal–N active sites in framework modulate...
