Amorphous materials are usually evaluated as photocatalytically inactive due to the amorphous nature-induced self-trapping of tail states, in spite their achievements electrochemistry. NiO crystals fail act an individual reactor for photocatalytic H2 evolution because intrinsic hole doping, regardless impressive cocatalytic ability proton/electron transfer. Here we demonstrate that two-dimensional nanostructure can efficient and robust photocatalyst solar without any cocatalysts. Further,...
An in-depth perspective on the role that N heteroatoms in 2D ZnIn<sub>2</sub>S<sub>4</sub> play improving photocatalytic properties.
Codoping of N and O in ultrathin graphitic carbon nitride (g-C3 N4 ) nanosheets leads to an inner electric field. This field restrains the recombination photogenerated carriers and, thus, enhances hydrogen evolution. The layered structure codoped g-C3 (N-O-CNNS) not only provides abundant sites contact with reaction medium, but also decreases distance over which electron-hole pairs are transported interface. Quantum confinement results increased bandgap makes photocatalytic more favorable...
Fe<sub>2</sub>O<sub>3</sub>has drawn significant attention in photocatalysis due to its natural abundance, thermodynamic stability, environmental compatibility, low toxicity and narrow bandgap.
Hybrid Bi12TiO20/Bi4Ti3O12 composites with different Bi : Ti molar ratios were successfully fabricated using a one-step solid-state calcination. These samples characterized X-ray diffraction, specific surface area analysis, scanning electron microscopy, high-resolution selected-area photoelectron spectroscopy, UV-vis diffuse reflection photoluminescence analyses, and photocurrent electrochemical impedance spectroscopy. Some specified techniques also used to investigate the photocatalytic...
Mullite-type oxides are widely recognized for their robust catalytic properties in oxidation reactions, whereas enhancing activity through effective surface modifications remains an important challenge. In this study, we synthesized a MnSO4-SmMn2O5 composite mullite by treating SmMn2O5 with sulfuric acid, resulting the formation of surface-modified MnSO4 species. This strategy significantly altered chemical oxide support, creating optimal platform Pt deposition via atomic layer deposition....
The modulation of the electronic structure CdS/a-MoOx nanocomposite during photocatalytic hydrogen evolution is significant to improve its performance in solar-hydrogen evolution. In this study, enhancement by reforming band was achieved. addition, mechanism investigated. initial photoinduced electrons excited CdS were found display strong reduction ability and transferred a-MoOx, which Mo6+ reduced Mo5+. This transformation led situ reconstruction, considerable for promotion H2 performance....
Abstract Exploring novel materials with intrinsic self‐trapped excitons (STEs) is crucial for advancing optoelectronic technologies. In this study, 2D 3R‐phase ZnIn 2 S 4 , featuring broken inversion symmetry introduced to investigate STEs. This material exhibits a broadband photoluminescence (PL) emission full width at half maximum of 164 nm and large Stokes shift ≈0.6 eV, which arises from the distortion [ZnS ] 6‐ tetrahedral unit induced by breaking strong electron‐phonon coupling. The...

Amorphous carbon nitrogen (a-CN) has attracted a lot of attention due to its unique properties, different from those crystal form. Here, we demonstrate near-infrared (NIR) photothermal conversion assisted photocatalytic hydrogen evolution a-CN with vacancies (a-CNN) nanosheets. Experiments suggest that sp2 hybridized C[double bond, length as m-dash]C structures can be created in a-CNN. These structures, just like small islands, disperse on a-CNN, leading fluorescence quenching and superior...
