When used as a photocatalyst, titanium dioxide (TiO2) absorbs only ultraviolet light, and several approaches, including the use of dopants such nitrogen, have been taken to narrow band gap TiO2. We demonstrated conceptually different approach enhancing solar absorption by introducing disorder in surface layers nanophase TiO2 through hydrogenation. showed that disorder-engineered nanocrystals exhibit substantial solar-driven photocatalytic activities, photo-oxidation organic molecules water...
Recent progress and strategies toward solar water splitting over heterogeneous semiconductors are reviewed the challenges future perspectives suggested.
TiO2 - xNx nanoparticles were prepared by employing the direct amination of 6−10-nm-sized titania particles. Doping on nanometer scale led to an enhanced nitrogen concentration up 8%, compared ≤2% in thin films and micrometer-scale powders. The synthesized nanocrystals are catalytically active absorb well into visible region 600 nm, thus exemplifying use a nanostructure-based synthesis as means producing novel photocatalytic materials.
Using a simple nanoscale exclusive synthesis route, TiO2-xNx photocatalysts that can be tuned to absorb across the visible region are produced in seconds at room temperature. The formed by employing direct nitridation of anatase TiO2 nanostructures with alkylammonium salts. Depending on degree nanoparticle agglomeration, catalytically active structured particles obtained whose absorption onset extends well into λ ∼ 550 nm. introduction small quantity palladium form chloride or nitrate...
A series of titania (TiO2)-based nanometer-sized photocatalysts, including nitrogen-doped TiO2 nanoparticles (NPs), are investigated using X-ray photoelectron spectroscopy (XPS). Conclusive evidence is obtained for O−Ti−N bond formation during the doping process. Therefore, this substitutional held accountable significant increase in photocatalytic activity NPs.
Here, we report, for the first time, hydrogenated TiO2 nanocrystals as a novel and exciting microwave absorbing material, based on an innovative collective-movement-of-interfacial-dipole mechanism which causes collective-interfacial-polarization-amplified absorption at crystalline/disordered anatase/rutile interfaces. This is intriguing upon further exploration may trigger other new concepts applications. As service to our authors readers, this journal provides supporting information...
Microwave absorbing materials have received considerable interest over the years for their applications in stealth, communications, and information processing technologies. These often require functionalization at nanoscale so to achieve desirable dielectric magnetic properties which induce interaction with incident electromagnetic radiation. This article presents a comprehensive review on recent research progress of nanomaterials microwave absorption, including basic mechanism absorption...
The development of distinguished photocatalysts with high photo-carrier disassociation and photo-redox power for efficient elimination pollutants in water is great significance but still a grand challenge. Herein, novel Cd0.5Zn0.5S/Bi2WO6 S-scheme heterojunction was built up by integrating Cd0.5Zn0.5S nanoparticles on Bi2WO6 microspheres via simple route. charge transfer mode substantially boosts the high-energetic electrons/holes spatial detachment conservation (reduction) (oxidation),...
The recent discovery of "black" TiO2 nanoparticles with visible and infrared absorption has triggered an explosion interest in the application a diverse set solar energy systems; however, what black nanoparticle really is remains mystery.

The construction of exceptionally robust and high-quality semiconductor-cocatalyst heterojunctions remains a grand challenge toward highly efficient durable solar-to-fuel conversion. Herein, novel graphitic carbon nitride (g-C3N4) nanosheets decorated with multifunctional metallic Ni interface layers amorphous NiS cocatalysts were fabricated via facile three-step process: the loading Ni(OH)2 nanosheets, high-temperature H2 reduction, further deposition nanosheets. results demonstrated that...
Phosphorus-doped graphitic carbon nitrides (P-g-C3N4) have recently emerged as promising visible-light photocatalysts for both hydrogen generation and clean environment applications because of fast charge carrier transfer increased light absorption. However, their photocatalytic performances on CO2 reduction gained little attention. In this work, phosphorus-doped g-C3N4 nanotubes are synthesized through the one-step thermal reaction melamine sodium hypophosphite monohydrate (NaH2PO2·H2O)....
Present photocatalysts for the synchronous cleanup of pharmaceuticals and heavy metals have several drawbacks, including inadequate reactive sites, inefficient electron–hole disassociation, insufficient oxidation reduction power. In this research, we sought to address these issues by using a facile solvothermal-photoreduction route develop an innovative plasmonic S-scheme heterojunction, Au/MIL-101(Fe)/BiOBr. The screened-out Au/MIL-101(Fe)/BiOBr (AMB-2) works in durable high-performance...
The rational design of sustainable noble-metal-free heterojunctions remains a key challenge for highly efficient and durable photocatalytic H2 production. In this study, it was revealed that the robust copper phosphide (Cu3P) nanoparticles may serve as cocatalyst p-type semiconductor at low (1.5 wt %) high (10 loading contents, respectively. Both Cu3P could evidently boost visible-light-driven production over graphitic carbon nitride (g-C3N4) nanosheets. Comparably speaking, heterojunction...
