Photocatalytic H2 Generation In article number 2000504, Hua Tang and co-workers designed a promising ternary photocatalyst CoO/TCN/Au heterostructure via integrating Au CoO nanoparticles with g-C3N4 hollow nanotubes. Localized surface plasmon resonance (LSPR) of promoted charge-carrier generation in g-C3N4, the appropriate band alignment between boosted hot electrons transfer from to which acti...

ZrO2 @g-C3N4 photocomposite has been prepared from nanoparticles and g-C3N4 nanosheet using methanol via the ultrasonic method. The was characterized XRD, TEM, EDX, DRS, FTIR, XPS techniques compared with pure g-C3N4. A comparative study between photocatalytic performance of nanocomposite material used to degrade indigo carmine (IC) dye in an aqueous suspension developed. experimental photodegr...

MoS2–C3N4 composite materials with Mo content from 0.3 to 9 wt% have been prepared by means of one-pot synthesis ammonium thiomolybdate (NH4)2MoS4 and urea-thiourea mixture. The solids were characterized several physical techniques tested in the thiophene hydrodesulfurization model reaction (HDS) photocatalytic hydrogen evolution (PHER). Transmission electron microscopy (TEM) X-ray absorption s...

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...

Graphitic carbon nitride (g-C3N4) with photo-attached platinum (Pt@g-C3N4) is known to generate hydrogen under illumination in aqueous environments the presence of carbohydrate hole quenchers. Here, Pt@g-C3N4 embedded into a polymer intrinsic microporosity (PIM-1) host material molecularly rigid structure maintain active unblocked catalyst surfaces and control transport to/from photocatalyst. A...

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...

Light elements-based materials are of relevant interest because of their specific physicochemical properties mainly dependent on the involved strong chemical bonds. Among them, diamond and c-BN are still today the most representative materials especially concerning super hardness property. Nevertheless, since the prediction by Liu and Cohen (on the basis of ab initio calculation) of theoretical...

The recent development in the field of superhard materials with Vickers hardness of >40 GPa is reviewed. Two basic approaches are outlined including the intrinsic superhard materials, such as diamond, cubic boron nitride, C3N4, carbonitrides, etc. and extrinsic, nanostructured materials for which superhardness is achieved by an appropriate design of their microstructure. The theoretically predi...

Photocatalytic hydrogen production is considered as an ideal approach to solve global energy crisis and environmental pollution. Graphitic carbon nitride (g-C3N4) has received extensive consideration due its facile synthesis, stable physicochemical properties, easy functionalization. However, the pristine g-C3N4 usually shows unsatisfactory photocatalytic activity limited separation efficiency ...
