Conventional TiO(2)-based photocatalysts oxidize NO(x) to nitrate species, which do not spontaneously desorb and therefore deactivate the catalyst. We show that selectivity of this reaction can be changed by creating a large concentration oxygen vacancies in TiO(2) nanoparticles through thermal reduction reducing atmosphere. This results photoreduction nitric oxide (NO) N(2) O(2), species at room temperature. The activity greatly enhanced doping with Fe(3+), an acceptor-type dopant...
The incorporation of Fe as a dopant in anatase TiO2 nanoparticles has been systematically investigated with the aim changing coordination geometry Ti via formation oxygen vacancies. Although Fe3+ ions are present solution during growth nanoparticles, high-temperature heat treatment is found to be necessary incorporate substituent for Ti4+ bulk nanoparticles. acceptors charge-compensated by vacancies, up concentrations high 10%. surprisingly solubility attributed very similar radii and...
Plasmon-driven photochemical N<sub>2</sub> fixation in pure water can be realized over MoO<sub>3−x</sub> nanosheets under visible to NIR excitation.
The suppression of energy migration-mediated surface quenching with increasing temperature leads to the abnormal thermo-enhanced photoluminescence LNP.
In this work, novel CuGaS2-ZnS p-n type semiconductor nanoheterostructures were synthesized by a solution route, and demonstrated experimentally to be very promising visible light active photo-catalyst for water-splitting hydrogen production. The construction of heterostructures follows multi-step strategy, employing Cu1.94S nanocrystals first as catalytic assistants the hetero-growth ZnS on their surfaces, then sacrificial seeds formation CuGaS2. Excitingly, attributed efficient charge...
The adsorption and release of nitrogen oxide (NO) molecules at the surface Fe-doped TiO2 nanoparticles, made by a template-free sol–gel process, has been studied. Fe3+ ions are found to be highly effective NO sites in Fe/TiO2. Up ∼89 μmol g−1 adsorbed can released exposure trace amounts H2O, which exceeds water-induced capacity other storage materials least factor 2. surprising efficiency water as trigger molecule for is due its large dipole moment, causes much stronger coordination species...
The double vacancies synergistically contribute to photocatalytic activity by affecting the separation and transfer efficiency of photo-generated carriers.

Group IVB ions (Ti4+ and Zr4+ ) are employed to modify solution growth of W18 O49 nanocrystals. In the presence group ions, morphology produced monoclinic nanocrystals can be modulated from inhomogeneous shapes uniform an ultrathin nanobelt with (1‾ 01) lattice plane being main exposure surface. Interestingly, nanobelts exhibit a unique chemical activity against alkylamine radicals, probably originated highly increased extra tungsten oxygen atoms inserted in regular lattice, which makes this...
Calcined Cu-based metal–organic frameworks impregnated with nickel nitrate catalysts (CuNi@C) were synthesised. X-Ray diffraction, scanning electronic microscopy, energy dispersive X-ray spectrometry, and photoelectron spectroscopy techniques applied for the characterisation of synthesised catalyst, which revealed an octahedral particle shape, rough surface, metallic copper (Cu, CuO) (Ni, NiO) particles.

Semiconductor materials play an important role in converting solar energy to electrical chemical as a photoanode realize photoelectrochemical conversion. Tantalum nitride (Ta3N5) semiconductor with suitable band gap and appropriate positions is considered be one of the best materials. However, poor charge-carrier separation efficiency mobility greatly limit its wide application field. Porous single crystal ordered lattice structural coherence large surface area are expected improve...
