2024年2月1日 · Compared to bulk g-C 3 N 4, CNNs possess 2D sheet structure and abundant mesoporous structure, making them exhibit great prospects in the following aspects: (1) larger specific surface area, thus exposing more active sites for trapping and activating reactants, and synchronously promoting mass transfer [36]; (2) abundant mesoporous structure ...

2023年11月1日 · In this paper, a rapid post-treatment at high temperature was developed to obtain g-C 3 N 4 nanosheets with abundant crystalline/amorphous interfaces to form homojunctions, which optimized uniplanar carrier mobility dynamics.

2024年9月15日 · Sheet-like Fe2O3 was prepared by using a new simple C3N4 templating method under mild condition. A novel drop-coating method was developed to fabricate Fe2O3/rGO hybrid electrode with hierarchical layered structure. A high capacity of 511 mAh g-1 at 5000 mA g-1 was obtained after 4000 cycles.

2016年1月12日 · We have realized in-situ growth of ultrathin ZnIn 2 S 4 nanosheets on the sheet-like g-C 3 N 4 surfaces to construct a “sheet-on-sheet” hierarchical heterostructure. The as-synthesized ZnIn...

2020年1月24日 · Poly (triazine imide) (PTI), a crystalline g-C 3 N 4, hosting two-dimensional nanoporous structure with an electron density gap of 0.34 nm, is highly promising for high-temperature hydrogen sieving because of its high chemical and thermal robustness. Currently, layered PTI is synthesized in potentially unsafe vacuum ampules in milligram quantities.

2024年9月23日 · In the study, a simple and effective secondary calcination method has been developed to successfully fabricate ultrathin white g-C 3 N 4 nano-sheets. The mass ratio of the same volume of bulk g-C 3 N 4 and white g-C 3 N 4 nano-sheets was as high as 50:1.

2023年8月20日 · The as-prepared p–n heterojunction ZnCo2O4/nitrogen-rich g-C3N4 sheet was used as visible light-induced photocatalysts for the photodegradation of p-Nitrophenol. The photocatalysts were analyzed using a variety of methods, including XRD, FTIR, FE-SEM, TEM, PL, BET, and UV–Vis DRS.

2024年3月29日 · This study offers a simple surfactant-assisted deposition coreduction procedure for producing non-noble bimetallic nanoparticles supported on graphitic carbon nitride (g-C3N4). The nanocomposite wa...

C3N4 crystallizes in the hexagonal P-6m2 space group. The structure is two-dimensional and consists of one C3N4 sheet oriented in the (0, 0, 1) direction. there are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms.

ZnIn2S4–g-C3N4 sheet-on-sheet nanocomposites with different g-C3N4 contents were synthesized by a facile hydrothermal method and characterized by thermogravimetric analysis (TGA), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR), transmission electron
