Increased photocatalytic activity of tube-brush-like ZnO nanostructures fabricated by using PVP nanofibers as templates

Fabrication and study of UV-shielding and photocatalytic performance of uniform TiO2/SiO2 core-shell nanofibers via single-nozzle co-electrospinning and interface sol–gel reaction

“…There are some reports showing that PVP and PAN polymers are good templates, which enhance photocatalytic e ciency of tube-brushlike ZnO nanostructures, and BiOBr nanosheets and Fe (III)-amidoximated, respectively [23,30,31]. PAN and PVP polymer matrixes were used to fabricate a 1D core-shell structure that promoted UVshielding e ciency and photocatalytic performance of core-shell structure.…”

ALD coating of centrifugally spun polymeric fibers and postannealing: case study for nanotubular TiO2 photocatalyst

“…[39][40][41] The electrospun polymer fibers were subsequently coated by ALD with TiO 2 , 11,[42][43][44][45][46] Al 2 O 3 10,47-49 or ZnO. 44,[50][51][52][53] In all aforementioned reports the diameters of the electrospun fibers were limiting the diameters of the resulting nanotubes to the range between tens and few hundreds of nm. No report employed fibers with larger diameters, up to the sub-micron scale.…”

Enhanced Photocatalytic Performance of ZnO through Coupling with Carbon Materials

“…Zinc oxide (ZnO), as an important photocatalyst, has received much attention due to its excellent properties such as low cost, high redox potential, nontoxicity, and environmental friendness. [18][19][20][21][22] ZnO has wide band gap (3.37 eV) and large exciton binding energy (60 meV). [23] Therefore, the main drawback that restricts its application is its fail to absorb visible light (~43% of solar spectrum), only absorbing UV light (~4% of solar spectrum).…”
