Urchinlike TiO2 spheres with tunable chamber structure were synthesized using a template-free solvothermal method. The unique sphere-in-sphere allows multiple reflections of UV light resulting in greatly enhanced photocatalytic activity. This work provided novel structural platforms for materials and device applications.
Mesoporous Au/TiO2 nanocomposites with Au nanoparticles homogeneously embedded within crystalline TiO2 framework were synthesized using a simple one-pot assembly approach and exhibit significantly enhanced photocatalytic activity.
Abstract Oxygen vacancy (V O ) is one of the most common defects in metal oxides (MOs), which endow MOs with many unique physiochemical properties. Even though V engineering has been applied photo(electro)catalysis, there are still significant challenges understanding formation, structure, and property . The can be produced by treating under low oxygen atmosphere or vacuum ruled equilibrium while other types also generated simultaneously. Identifying distinguishing formation function Vo...
Sulfur-modification of the TiO2 was achieved by treating precursor (xerogel) under supercritical conditions in CS2/ethanol fluid. Nuclear magnetic resonance, X-ray photoelectron spectroscopy and Fourier transform infrared spectra demonstrated that modified S-species incorporated into network forming S−Ti−O bonds rather than adsorbed CS2. During liquid-phase photocatalytic degradation methylene blue (MB) visible light irradiation (>420 nm), as-prepared S-doped exhibited much higher activity...
N-doped TiO2 photocatalysts were prepared by pretreating the precursor in NH3/ethanol fluid under supercritical conditions, denoted as TiO2N(SC). In contrast to TiO2N(DC), obtained via direct calcination which N dopants mainly present form of surface adsorbed NH3 molecules, most TiO2N(SC) O-Ti-N and N-Ti-N nitrides, confirmed either X-ray photoelectron spectroscopy (XPS) or Fourier transform infrared (FTIR) spectra. During liquid-phase oxidative degradation phenol irradiation with UV light...
Fe-doped nanocrystalline TiO2 (Fe/TiO2) with a mesoporous structure was prepared via facile nonhydrolytic sol−gel (NSG) route. During photodegradation of methylene blue under visible light irradiation, as-prepared Fe/TiO2 exhibited higher activity than either the undoped or obtained traditional hydrolytic The correlation photocatalytic performance to structural characteristics is discussed based on detailed characterizations. promoting effect Fe-doping could be attributed formation...
Zeolite's mesoporous cousins: High-surface-area single-crystal-like anatase-TiO2 was synthesized by a simple solution-growth method. This method produces controllable network and preferential exposure of the highly active (001) planes (see TEM) is readily extendable to synthesis other single crystals for application in, example, catalysis energy storage. Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited...
A facile aerosol-spraying approach was developed to prepare mesoporous BiFeO(3) hollow spheres with enhanced activity and durability in visible photocatalysis.
A well-crystallized plasmonic MoxW1–xO3–y hybrid was obtained by a nonaqueous method. Detailed characterization means of XRD, TEM, Raman, UV–vis, N2 physisorption, and XPS measurements revealed that the synthesized showed strong localized surface plasmon resonance (LSPRs). It demonstrated such LSPRs generated from crystal vacancies, mainly including mutual doping vacancies molybdenum ions tungsten oxygen vacancies. More importantly, LSPR absorption intensity almost 20, 16, 8 times larger...
