Self-organized V-N co-doped TiO2 nanotube arrays (TNAs) with various doping amount were synthesized by anodizing in association hydrothermal treatment. Impacts of co-doping on the morphologies, phase structures, and photoelectrochemical properties TNAs films thoroughly investigated. The photocatalysts show remarkably enhanced photocatalytic activity for CO2 photoreduction to methane under ultraviolet illumination. mechanism is discussed detail.
Zr/N co-doped TiO2 nanostructures were successfully synthesized using nanotubular titanic acid (NTA) as precursors by a facile wet chemical route and subsequent calcination. These Zr/N-doped made NTA show significantly enhanced visible light absorption much higher photocatalytic performance than the P25 nanoparticles. Impacts of co-doping on morphologies, optical properties, activities precursor-based thoroughly investigated. The origin activity is discussed in detail.
A series of W, N codoped TiO 2 nanotube arrays with different dopant contents were fabricated by anodizing in association hydrothermal treatment. The samples characterized scanning electron microscopy, X-ray diffraction, photoelectron spectroscopy, and ultraviolet-visible light diffuse reflection spectroscopy. Moreover, the photocatalytic activity W was evaluated degradation methylene blue under visible irradiation. It found that TNAs exists forms Ti-N-O, while as 6+ substituting Ti lattice...
Highly ordered TiO2 nanotube arrays (TNAs) codoped with V and N were synthesized by electrochemical anodization in association hydrothermal treatment. The samples characterized field emission scanning electron microscopy, X-ray diffraction photoelectron spectroscopy. photocurrent photocatalytic activity of investigated under visible light irradiation. Moreover, the production hydroxyl radicals (·OH) on surface light-irradiated is detected a photoluminescence technique using terephthalic acid...
Mo,N‐codoped TiO 2 nanotube arrays (TNAs) were fabricated by a two‐step method consisting of electrochemical anodization and subsequent magnetron sputtering Mo. The samples characterized scanning electron microscopy (SEM), X‐ray diffraction (XRD), photoelectron spectroscopy (XPS), ultraviolet‐visible diffuse reflectance (UV‐Vis DRS). results showed that the exhibited higher visible light absorbance remarkably enhanced photocurrent density photocatalytic activity compared with single N‐doped...
To extend the photo response of TiO2 further into visible light region, nanotube arrays codoped with vanadium and nitrogen were synthesized by anodization process, followed impregnation calcination process. X-ray photoelectron spectroscopy (XPS) revealed existence interstitial N V (V4+ V5+) in V, catalysts, which was beneficial to narrow bandgap separating charges. Higher photocurrent density displayed showed that more photo-induced electrons generated, therefore effectively improved...
The group 2 σ factor for RNA polymerase SigE plays important role in regulating central carbon metabolism cyanobacteria. However, the regulation of these pathways at a proteome level remains unknown. Using sigE-deficient strain (ΔsigE) Synechocystis sp. PCC 6803 and quantitative proteomics, we found that depletion induces differential protein expression sugar catabolic including glycolysis, oxidative pentose phosphate (OPP) pathway, glycogen catabolism. Two debranching enzyme homologues...
