The molecular complexes between barbituric acid (BU) and chloranilic (ChA) over graphitic nitride (g-C3N4) are investigated. the nanocomposite were investigated both in solid state methanol. corresponding using FTIR, TGA, UV-Vis spectroscopy. structures explored DFT calculations wB97XD/ def2-TZVP basis set. revealed formation of hydrogen-bonded complexes, which initiate proton transfer from ChA...
We propose an efficient method to synthesize large-scale soluble acidified graphitic carbon nitride (g-C3N4). The as-prepared material exhibits the characteristics of a poly-ammonium salt and is soluble in several solvents with good dissolution-recrystallization reversible equilibrium. The pH value- and temperature-dependent solubility of the acidified g-C3N4 facilitates its separation and puri...
Pharmaceuticals and personal care products (PPCPs) have attracted widespread attention due to their durability the environment. Therefore, it is highly desirable develop new technologies that are environmentally friendly, energy saving, compatible degrade these pollutants. In this study, a vis–NIR-driven efficient S-scheme photocatalyst, WO3−x /S doped g-C3N4, used for PPCPs degradation. The re...
Normal photocatalysts cannot effectively remove low-concentration NO because of the high recombination rate photogenerated carriers. To overcome this problem, S-scheme composites have been developed to fabricate photocatalysts. Herein, a novel Sb2WO6/g-C3N4 nanocomposite was fabricated by an ultrasound-assisted method, which exhibited excellent performance for photocatalytic ppb-level removal. ...
A new type of graphitic C3N4-based composite photocatalysts was designed and prepared by co-loading PEDOT as a hole transport pathway and Pt as an electron trap on C3N4. The as-prepared C3N4-PEDOT-Pt composites showed drastically enhanced activity for visible light-driven photocatalytic H2 production compared to those of C3N4-PEDOT and C3N4-Pt, possibly due to the spatial separation of the redu...
Graphitic carbon nitride (g-C3N4) is a visible light photocatalyst, limited by low activity mainly caused by rapid recombination of charge carriers. In the present work, honeycomb-like g-C3N4 was synthesized via thermal condensation of urea with addition of water at 450 °C for 1 h. Prolonging the condensation time caused the morphology of g-C3N4 to change from a porous honeycomb structure to a ...
Graphitic-C3N4(g-C3N4), a low-cost visible-light-driven photocatalyst, was used for the photocatalytic oxidation of aqueous methylene blue (MB) in the dark with Sr4Al14O25:(Eu,Dy) assistance. The Sr4Al14O25:(Eu,Dy)/g-C3N4 photocatalysts were fabricated through the ultrasonic dispersion method. The commercial Sr4Al14O25:(Eu,Dy) phosphor was used as a long afterglow supplier for exciting g-C3N4 i...
A Ti species modified g-C3N4 photocatalyst was synthesized via an in situ hydrothermal route and the subsequent low-temperature calcination. The hydrothermal process results in not only the fabrication of TiO2/g-C3N4 heterojunctions, but also the coordination between Ti species and g-C3N4, which are verified by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The electrical r...
Nitrobenzene (NB) is toxic even at low concentrations and hence its contamination in the environment a pervasive concern. The electrochemical techniques have emerged as rosy method to sense degrade NB graphitic carbon nitride (g-C3N4) catalysts are found be promising for this. In this study, silver nanoparticles (AgNPs)-decorated n-[3-(trimethoxysilyl)propyl]ethylenediamine (EDAS)-modified nano...
The g-C3N4-coupling TiO2 photocatalysts with controllable particle size as well as the interface contact were prepared by a general nonaqueous sol-gel method. The structural and morphological features of g-C3N4/TiO2 were investigated through the X-ray diffraction, Fourier transformed infrared spectra, scanning electron microscopy and transmission electron microscopy, respectively. It is found t...
