O-doped g-C3N4 was synthesized for the first time by a facile H2O2 hydrothermal approach. The O-doping in lattice could induce intrinsic electronic and band structure modulation, resulting its absorbance edge up to 498 nm enhanced visible-light photoactivity, consequently.
Nitrogen-deficient graphitic carbon nitride (g-C3N4−x) was synthesized by a hydrothermal treatment using ammonium thiosulfate as an oxidant. The as-prepared photocatalyst characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption–desorption, Fourier transform infrared (FTIR) spectroscopy, photoelectron spectroscopy (XPS), elemental analysis (EA), paramagnetic resonance (EPR), UV-vis diffuse reflectance (UV-vis DRS) and photoluminescence (PL) spectroscopy....
The controlled synthesis of two novel h-WO3 hierarchical structures made nanorods/nanowires has been successfully realized in a large scale via simple hydrothermal method. It is demonstrated that the morphology final products significantly influenced by adding different sulfates. urchinlike and ribbonlike WO3 can be selectively prepared Rb2SO4 K2SO4, respectively. evolvement growth mechanism were studied carefully. sulfate-induced oriented attachment proposed for possible formation sample....
The TiO2-N-x%WO3 composite photocatalysts were prepared by introducing WO3 into nitrogen-doped TiO2. catalysts present much higher photocatalytic activity than TiO2 and under both ultraviolet visible light irradiation. Diffuse reflectance UV-vis spectra, XPS analysis, IR spectra show that the coordinated nitrogen species (or N-metal-O linkages) may contribute to activity. coupling increases active thus enhances of photocatalysts. superior upon UV irradiation can be rationalized in terms...
Efficient electron transfer for high photocatalytic H<sub>2</sub> evolution was obtained by immobilizing ZnS nanoparticles on the nanosheets of graphene and MoS<sub>2</sub>.
Graphitic carbon nitride (g-C3N4) hybridized with a small number of multi-walled nanotubes (CNT) was synthesized using cyanamide as precursor. The optimal CNT content is found to be ∼0.2 wt% in the composite, which displays 2.4-fold enhancement photocatalytic water splitting over pure g-C3N4. Characterizations by series joint techniques including Raman spectra, UV/vis diffuse reflectance steady and time-resolved fluorescence emission photocurrent responses were carried out, aiming reveal...
For the first time, a single crystalline FeTiO3 nanodisc in ilmenite phase has been synthesized by hydrothermal reaction at 220 °C. The prepared was hexagonal disk-like structure with an average diameter of ∼400 nm and thickness ∼70 nm, while its face oriented (001) plane grown to (110) direction. heterojunction formed between as-prepared Degussa P25 particle size ∼25 employing maleic acid as organic linker. FeTiO3/TiO2 coupled nanoscale demonstrated greatly enhanced photocatalytic activity...
Abstract The development of metal‐free photocatalysts with high efficiency, stability, and broadband solar absorption is a major challenge to realize green sustainable chemical development. Recently, nanohybrids (BP/CN) composed black phosphorus (BP) polymeric carbon nitride (CN) are emerged as photocatalytic hybrids light‐harvesting capabilities higher performance. Herein, the latest progress BP/CN for multifarious photoredox reactions summarized. different heterojunction types hybrid...
Deprotonation of g-C<sub>3</sub>N<sub>4</sub> with Na ions successfully inhibits the unfavorable H<sub>2</sub>O<sub>2</sub> intermediate in a photocatalytic process, and significantly facilitates nonsacrificial water splitting under visible light.
Abstract 2D covalent organic frameworks (COFs) are drawing intense attention in heterogenous photocatalysis due to their porous, crystalline, and tailor‐made structures. For highly efficient solar‐to‐chemical energy conversion, revealing modulating active centers the skeletons of COFs great importance but encounter severe challenges. Herein, it is demonstrated that cyano conjugation on a typical β‐ketoenamine‐linked COF via aldehyde‐imine Schiff‐base condensation contributes an enhanced...
Incorporating CdS nanoparticles into the interlayer of ZnCr–LDH nanosheets led to formation CdS-pillared nanohybrid, which exhibited superior photocatalytic hydrogen-generation performance from water splitting.
In this paper we have prepared Bi<sub>2</sub>S<sub>3</sub>@SiO<sub>2</sub> nanorods designed as binary contrast agents for a non-invasive and real-time visualization of the gastrointestinal tract.
Semiconductor photocatalysis is a potential pathway to solve the problems of global energy shortage and environmental pollution. Black phosphorus (BP) has been widely used in field owing its features high hole mobility, adjustable bandgap, wide optical absorption range. Nevertheless, pristine BP still exhibits unsatisfactory photocatalytic activity due low separation efficiency photoinduced charge carriers. In recent years, construction heterostructured photocatalysts based on become...
The large-scale synthesis of single-crystal K(x)WO(3) tungsten bronze nanowires has been successfully realized by a hydrothermal method under mild conditions. Uniform K(0.33)WO(3) with diameters 5-25 nm and lengths up to several micrometers are obtained. It is found that the morphology crystallographic forms final products strongly dependent on sulfate citric acid, which may act as structure-directing soft-reducing agent, respectively. Some other influential factors growth nanowires, such...
