Both non-metallic g-C3N4 and BiVO4 are novel photocatalysts responsive to visible light, but their low charge separation efficiency restricts inconspicuous photocatalytic activity. In this paper, direct Z-type g-C3N4/BiVO4 photocatalyst was constructed by calcination hydrothermal for the degradation of methylene blue. The existence heterojunction confirmed detailed study its chemical structure ...

In order to recover lithium from brine with a high Mg2+/Li+ ratio, positively charged nanofiltration (NF) membrane was prepared by depositing polydopamine (PDA)-coated graphitic carbon nitride (g-C3N4) as the interlayer (PDA-g-C3N4) and interfacial polymerization (IP) of polyethyleneimine (PEI) trimesoyl chloride (TMC) carried out. Under optimal conditions, water contact angle composite is only...

Abstract. Graphitic carbon nitride (g-C3N4) is a photocatalyst that has recently been given lot of attention due to its effectiveness in wastewater and environmental treatment, solar energy utilization, biomedical applications, etc. In this study, g-C3N4 was synthesized characterized carry out the degradation metoprolol tartrate salt (MET), which classified as an emerging contaminant. MET one m...

Half-metallicity rising from the s/p electrons has been one of the hot topics in spintronics. Based on the first-principles of calculation, we explore the magnetic properties of the B-doped graphitic heptazine carbon nitride (gh-C3N4) system. Ferromagnetism is observed in the B-doped gh-C3N4 system. Interestingly, its ground state phase (BC1@gh-C3N4) presents a strong half-metal property. Furth...

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...

Graphitized carbon nitride (g-C3N4), as a simple and green photocatalytic material, has been widely used in degradation. However, the activity of g-C3N4 was inhibited by poor visible light absorption high photocarrier recombination rate. Metal quantum dots (Qds)/g-C3N4 nanosheets coupled catalysts have attracted more attention Fenton advanced oxidation process due to their charge mobility activ...
