A solvothermal self-made composite of graphitic carbon nitride (g-C3N4) and commercially available titanium dioxide (TiO2) demonstrated the removal commercial acid green-25 (AG-25) textile dye in a saline water matrix when activated by ultraviolet (UV) visible light. The g-C3N4-TiO2 was characterized X-ray diffraction (XRD), Nitrogen sorption–desorption recording modeling Brunauer–Emmett–Teller...

The introduction of a metallic cocatalyst is good strategy for achieving high carrier density and absorbing photons under wide-spectrum illumination. Herein, WO2/g-C3N4 nanocomposites were designed synthesized the first time using simple calcination method to enhance photocatalytic performance. exhibited significant properties: visible light irradiation, 4 wt% an RhB degradation 96% in 120 min....

Although there are several reports about the beneficial performance of metal doped graphitic carbon nitrides (g-C3N4) in various photocatalytic reactions, effect different alkali dopants has not been studied systematically. Series undoped, Li-, Na- and K-doped samples was synthetized used for preparation novel type photocatalysts, composed palladium nanoparticles supported on metals-doped nitri...

Photocatalytic hydrogen evolution reaction (PC-HER) provides a solution to energy crisis and environmental pollution. Herein, different graphitic carbon nitride (g-C3N4)-based van der Waals (vdW) type II homojunctions have been fabricated g-C3N4/K-doped g-C3N4 nanosheets an outstanding PC-HER rate of 1,243 µmol-h?1·g?1 under visible light, higher than that bulk g-C3N4, doped nanosheets, mixed n...

Ultraviolet position-sensitive detectors (PSDs) are expected to undergo harsh environments, such as high temperatures, for a wide variety of applications in military, civilian, and aerospace. However, no report on relevant PSDs operating at temperatures can be found up now. Herein, we design new 2D/3D graphitic carbon nitride (g-C3N4)/gallium (GaN) hybrid heterojunction construct the ultraviole...

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.

Graphitic-C3N4 is shown for the first time to catalyse photoacetalization of aldehydes/ketones with alcohols to acetals in high yields using visible light under ambient conditions; transient charge separation over the material is effective to catalyse the reaction in the absence of Lewis or Brønsted acids, giving a new green alternative catalyst.

The pursuit of operational advancements in direct formic acid fuel cells (DFAFCs) necessitates the development high-performance platinum (Pt)-based catalysts for electrooxidation (FAOR). However, FAOR on Pt-based follows a dual pathway mechanism, which is preferred route due to its efficient dehydrogenation process. Conversely, indirect results generation adsorbed CO species, process that delet...
