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.

2016年1月14日 · Here, atomically thin mesoporous nanomesh of graphitic carbon nitride (g-C 3 N 4) is fabricated by solvothermal exfoliation of mesoporous g-C 3 N 4 bulk made from thermal polymerization of freeze-drying assembled Dicyandiamide nanostructure precursor.

2021年12月1日 · Ultrathin graphitic carbon nitride (g-C3N4) nanosheets were prepared by the glucose assisted exfoliation of the bulk g-C3N4. The product retained the basic structure and optical properties of g-C3N4 and is fully characterized. The product showed excellent photocatalytic performance in the visible region, which was 4 times better than the bulk.

2016年10月20日 · In this paper, we reported the experimentally achieving of high temperature ferromagnetism in metal-free ultrathin g-C 3 N 4 nanosheets by introducing of B atoms.

2021年10月27日 · The atomically thin nanosheets of graphitic carbon nitride (g-C 3 N 4) with mesopores have been successfully exfoliated with supercritical CO 2 (scCO 2). The thickness of the as-synthesized samples could be directly tailored by simply regulating the scCO 2 pressure.

2 天之前 · The rapid and effective removal of pharmaceuticals and personal care products (PPCPs) from groundwater is challenging. In this paper, porous cyano group-rich g-C3N4 catalysts were prepared by urea (U) and a KOH-assisted thermal polymerization strategy. The thickness, active sites, and pores of g-C3N4 were successfully modulated by urea and KOH-assisted thermal polymerization. In addition, the ...

Electrons act as bridges promoting photocatalysis and Fenton reactions. Ultra-thin g-C 3 N 4 /FeOCl can efficiently remove pollutants and antibacterial.

2023年1月25日 · Herein, the physicochemical properties and enhanced adsorption capacity of highly porous thin-layer graphitic carbon nitride (g-C 3 N 4) nanosheets (CNNs) in relation to the separation of dyes are investigated. Cationic and anionic dyes with similar sizes are adopted to study the adsorption and separation properties of graphitic carbon nitride.

In situ growth of the metal–organic framework material MFM-300 (Fe) on an ultra-thin sheet of graphitic carbon nitride (g-C3N4) has been achieved via exfoliation of bulk carbon nitride using supercritical CO2.

2015年6月19日 · Here, a simple one-step ball milling method is presented for synthesis of mechanically exfoliated g-C 3 N 4 (MECN) thin nanosheets at large scales for the first time. Characterization results showed that gradual size reduction, accompanied by a continual bandgap absorption shift, occurred with increasing grinding time.
