“…Compared with P25 (3.3 eV) and ZTOF‐1‐P10 (3.0 eV), the band‐gap energy of the ATC‐P10 (Figure b) was calculated to be about 2.9 eV. Based on the above results, ATC‐P10 composite exhibits a strong UV‐light response due to the incorporation of Ag particles, resulting in a large amount of photogenerated electrons, which potentially ensures enhanced degradation efficiency under UV‐light , . This will be confirmed in the next catalytic experiment.…”

A series of Ag-enhanced TiO 2-x /C composites (Ag/TiO 2-x /C composites) with metal-organic frameworks (MOFs) as precursors were prepared, and their photocatalytic activities were evaluated by the UV-light driven photodegradation behaviors of methyl blue (MB). The as-obtained samples were characterized by several techniques such as SEM, XRD, N 2 -adsorption, XPS, UV/Vis spectrophotometry and UV/Vis diffuse-reflectance spectra.

“…The lattice spacing of 0.349, 0.240 and 0. 286 nm are due to the presence of N‐TiO 2 (NT), CuO and Co 3 O 4 ,respectively, within the composite CuCoNT NFs ,. The mesoporous NFs structure of composite CuNT NFs are confirmed by TEM and HR‐TEM images (Figure S3a,b).…”

One-dimensional mesoporous composite CuO À Co 3 O 4 /N-TiO 2 nanofibers (CuCoNT NFs) have been fabricated by in situ sol À gel electrospinning technique. In our approach, both polyvinylpyrrolidone (PVP) and polyethylene glycol (PEG) are used as dual polymeric carrier matrix for the fabrication of electrospun CuCoNT NFs. PVP chains assist the electrospinning of the uniform composite nanofibers whereas PEG is responsible for mesoporosity which is confirmed by N 2 sorption analyses. Along with CuCoNT NFs, other nanofiber samples (TiO 2 NFs, NTiO 2 NFs, CuO/N-TiO 2 NFs, Co 3 O 4 /N-TiO 2 NFs) have also been fabricated for comparative studies. The morphology and composition of the NFs have been confirmed by the HR-TEM and XPS analyses. The red shifting of band gap energy from anatase TiO 2 NFs to composite CuCoNT NFs (1.57 eV) is suggesting formation of visible light response. Oxygen vacancies in CuCoNT NFs, leads to lowering the e À À h + recombination. The lowering of photoluminescence spectrum and high photocurrent response in CuCoNT NFs makes CuO as low cost cocatalyst. The composite CuCoNT NFs is treated as an efficient photocatalyst for swift degradation of mixed dyes in visible light, an exemplary move. Exactly, 100% mixed dyes (30 mg/L) degradation is achieved at pH 10 in just 60 minutes.

“…There are several reports on this template-synthesis strategy for nanofabrication of 1D nanostructures, e.g. nanotubes and nanowire arrays [7,28,44,67,74,100], thanks to the confinement effect of template which could be thermally removed at the final step. However, the junctions prepared by template methods are difficult to be taken out from templates and are usually destroyed when dissolving templates.…”
