The photocatalytic performance of the star photocatalyst g-C3N4 was restricted by low efficiency because fast charge recombination. present work developed a facile in situ method to construct g-C3N4/g-C3N4 metal-free isotype heterojunction with molecular composite precursors aim greatly promote separation. Considering fact that samples prepared from urea and thiourea separately have different band structure, were treated simultaneously under same thermal conditions, creating novel layered...
In order to develop efficient visible light driven photocatalysts for environmental applications, novel polymeric g-C3N4 layered materials with high surface areas are synthesized efficiently from an oxygen-containing precursor by directly treating urea in air between 450 and 600 °C, without the assistance of a template first time. The as-prepared strong absorption have band gap around 2.7 eV. crystallinity specific increases simultaneously when heating temperatures increases. demonstrated...
Graphitic carbon nitride (g-C3N4) has been widely investigated and applied in photocatalysis catalysis, but its performance is still unsatisfactory. Here, we demonstrated that K-doped g-C3N4 with a unique electronic structure possessed highly enhanced visible-light photocatalytic for NO removal, which was superior to Na-doped g-C3N4. DFT calculations revealed K or Na doping can narrow the bandgap of atoms, intercalated into interlayer via bridging layers, could decrease localization extend π...

The photoresponsive range self-doped can be extended from UV to visible light and band gap continuously tuned. Density functional theory (DFT) calculation results that foreign ions are doped in caves constructed four adjacent effectively narrow lowering conduction position meanwhile generating impurity level. photocatalytic performance is...

The increase secondary inorganic pollutants (SO42−, NO3−, NH4+) PM2.5 was observed simultaneously at four sites, especially plain BTH, which could be identified as a common characteristic pollution east China. sulfate nitrate mainly formed heterogeneous reaction...
A facile and controllable in situ reduction strategy is used to create surface oxygen vacancies (OVs) on Aurivillius-phase Sr2 Bi2 Nb2 TiO12 nanosheets, which were prepared by a mineralizer-assisted soft-chemical method. Introduction of OVs the extends photoresponse cover whole visible region also tremendously promotes separation photoinduced charge carriers.

To achieve efficient photocatalytic air purification, we constructed an advanced semimetal-organic Bi spheres-g-C3N4 nanohybrid through the in-situ growth of nanospheres on g-C3N4 nanosheets. This Bi-g-C3N4 compound exhibited exceptionally high and stable visible-light performance for NO removal due to surface plasmon resonance (SPR) endowed by metal. The SPR property could conspicuously enhance harvesting charge separation. electromagnetic field distribution spheres involving effect was...
