Photocatalysis represents a promising technology that might alleviate the current environmental crisis. One of most representative photocatalysts is graphitic carbon nitride (g-C3N4) due to its stability, cost-effectiveness, facile synthesis procedure, and absorption properties in visible light. Nevertheless, pristine g-C3N4 still exhibits low photoactivity rapid recombination photo-induced ele...

Constructing a hierarchical structure with tunable pore size is practical method to improve the capacity of photocatalytic hydrogen production catalysts. In this work, titanium dioxide/graphitic carbon nitride (TiO2/g-C3N4) nanofibers meso/macro-porous are fabricated by combining one-step electrospinning and calcination process, in which developed introducing polyvinylpyrrolidone liquid paraffi...

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...

Highly efficient visible-light-driven heterogeneous photocatalyst Ag3PO4/g-C3N4 with different weight ratios from Ag3PO4 to g-C3N4 were synthesized by a facile in situ hydrothermal method and characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectrometry (FTIR), photoluminescence spectra (PL), UV–vis diffuse reflectance (UV-Vis), electrochemic...

Two-dimensional graphitic carbon nitrides (2D g-C3N4) are promising photocatalysts for water splitting to hydrogen due their non-toxicity and high stability. However, the bulk g-C3N4 has some intrinsic drawbacks, such as rapid electron–hole recombination low charge-carrier mobility, resulting in poor photocatalytic activity. Here, 2,4-diamine-6-phenyl-1,3,5-triazine was employed a precursor reg...

In this work, a g-C3N4/porphyrin nanocomposite was fabricated through the self-assembling of monomeric Tetrakis (4-carboxyphenyl) porphyrin (TCPP) molecules with g-C3N4 nanomaterials. The characterizing results showed good distribution TCPP nanofibers diameter < 100 nm and several micrometers in length on nanoflakes’ surfaces. prepared had two bandgap energies 2.38 2.7 eV, which could harves...
