Two types of photocatalysts, 1%Pt/Cd1?xZnxS/g-C3N4 (x = 0.2–0.3) and Cd1?xZnxS/1%Pt/g-C3N4 0.2–0.3), were synthesized by varying the deposition order platinum, a solid solution cadmium zinc sulfides onto surface g-C3N4. The characterization photocatalysts showed that, for 1%Pt/Cd1?xZnxS/g-C3N4, small platinum particles deposited sulfides; in case Cd1?xZnxS/1%Pt/g-C3N4, enlarged clusters located...

Hollow graphitic carbon nitride (HCN) ZrO2/g-C3N4 hybrid composites (HCN–ZR) and the target catalyst Fe/ZrO2/g-C3N4 (HCN–FZR) were prepared successfully by a solvo-thermal method and evaluated for photo-degradation of organic pollutants, i.e. MO, and herbicides, metsulfuron methyl (MTSM). These materials were characterized by a variety of techniques, including Fourier transform infrared spectro...

For the first time, it is demonstrated that the robust organic semiconductor g-C3N4 can be integrated into a nature-inspired water splitting system, analogous to PSII and PSI in natural photosynthesis. Two parallel systems have been developed for overall water splitting under visible light involving graphitic carbon nitride with two different metal oxides, BiVO4 and WO3. Consequently, both hydr...

Graphitic carbon nitride, g-C3N4, is a promising organic photo-catalyst for a variety of redox reactions. In order to improve its efficiency in a systematic manner, however, a fundamental understanding of the microscopic interaction between catalyst, reactants and products is crucial. Here we present a systematic study of water adsorption on g-C3N4 by means of density functional theory and the ...

Quantum dot (QD) sensitization can increase the light absorption and electronic transmission of photocatalysts. However, limited studies have been conducted on the photocatalytic activity of photocatalysts after modification by noble metal QDs. In this study, we developed a simple method for fabricating Pd-QD-modified g-C3N4. Results showed that the modification of Pd-QDs can improve the NO pho...

Piezoelectricity is a unique property of materials that permits the conversion of mechanical stimuli into electrical and vice versa. On the basis of crystal symmetry considerations, pristine carbon nitride (C3N4) in its various forms is non-piezoelectric. Here we find clear evidence via piezoresponse force microscopy and quantum mechanical calculations that both atomically thin and layered grap...

In this study, novel photocatalysts MVO4/g-C3N4 (M = La, Gd) were prepared by the hydrothermal method, through which different loading amounts of 10–50%MVO4 and g-C3N4 mixed ultrasonically oscillated to gain heterojunction catalysts. All samples characterized XRD, SEM, TEM, FT-IR, XPS, Us-vis, PL ensure successful integration LaVO4 GdVO4 with g-C3N4. The obtained results showed that could effec...

Ferromagnetic two-dimensional (2D) ultrathin nanosheets hold great promise for next generation electronics. Ferromagnetic metal-free materials that usually possess only an s/p electronic configuration with weak spin-orbit coupling and a large spin relaxation time, would play an important role in constructing future spintronic devices. However, the absence of an intrinsic spin ordering structure...

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...
