Surface-enhanced Raman scattering (SERS) substrates with high activity and stability are desirable for SERS sensing. Here, we report a new single atomic layer graphitic-C3N4 (S-g-C3N4) and Ag nanoparticles (NPs) hybrid as high-performance SERS substrates. The SERS mechanism of the highly stable S-g-C3N4/Ag substrates was systematically investigated by a combination of experiments and theoretica...

Interfacing carbon nanodots (C-dots) with graphitic carbon nitride (g-C3N4) produces a metal-free system that has recently demonstrated significant enhancement of photo-catalytic performance for water splitting into hydrogen [Science, 2015, 347, 970-974]. However, the underlying photo-catalytic mechanism is not fully established. Herein, we have carried out density functional theory (DFT) calcu...

Since the graphitic carbon nitride (g-C4N3), which can be seen as C-doped graphitic-C3N4 (g-C3N4), was reported to display ferromagnetic ground state and intrinsic half-metallicity (Du et al., PRL,108,197207,2012), it has attracted numerous research interest to tune the electronic structure and magnetic properties of g-C3N4 due to their potential applications in spintronic devices. In this pape...

Graphitic carbon nitride (g-C3N4), as the one of most promising photocatalysts, usually relies on noble metal co-catalysts in photocatalytic water splitting H2 evolution process, which greatly increases use cost. Here, a zeolite imidazole framework (ZIF-67) derived [email protected]/g-C3N4 composite was constructed through facile thermal condensation ZIF-67 and melamine. The obtained composites...

Atrazine is a systemic herbicide widely used in weed control. In recent years, it has been largely detected surface and groundwater several locations all over the world. Photocatalysis green sustainable technology with huge application prospects pollution control degradation of organic water pollutants. this work, photodegradation aqueous atrazine was investigated pristine graphitic carbon nitr...

The development of high catalytic performance heterogeneous catalysts such as peroxymonosulfate (PMS) activators is important for the practical remediation organic pollution caused by Rhodamine B (RhB). An economical and facile synthesized composite copper–magnesium oxide carbon nitride (CM/g-C3N4) was prepared sol-gel/high-temperature pyrolysis method to activate PMS RhB degradation. CM/g-C3N4...

Black TiO2 nanobelts/g-C3N4 nanosheets laminated heterojunctions (b-TiO2/g-C3N4) as visible-light-driven photocatalysts are fabricated through a simple hydrothermal-calcination process and an in-situ solid-state chemical reduction approach, followed by the mild thermal treatment (350 °C) in argon atmosphere. The prepared samples are evidently investigated by X-ray diffraction, Fourier transform...

Highly-monodispersed g-C3N4/TiO2 hybrids with a core/shell structure were synthesized from a simple room temperature impregnation method, in which g-C3N4 was coated through self-assembly on the commercially available Degussa P25 TiO2 nanoparticles. Structural and surface characterizations showed that the presence of g-C3N4 notably affected the light absorption characteristics of TiO2. The g-C3N...

Graphitic carbon nitride (g-C3N4), a metal-free semiconductor with a band gap of 2.7 eV, has received considerable attention owing to its fascinating photocatalytic performances under visible-light. g-C3N4 exhibits high thermal and chemical stability and non-toxicity such that it has been considered as the most promising photocatalyst for environmental improvement and energy conservation. Hence...

In this study, unique hybrid structures were constructed between a Ce-based metal-organic framework (Ce-MOF) and graphitic carbon nitride (g-C3N4) materials. addition, the g-C3N4 materials used for these heterostructures prepared by five different methods, namely conventional pyrolysis method, chemical exfoliation strong acid, activation an alkaline hydrothermal treatment, melamine-cyanuric aci...
