Photocatalytic and Self-Cleaning Properties of Ag-Doped TiO2
Commercially available TiO2 of anatase structure produced in the Chemical Factory Police S.A. was modified by doping Ag from AgNO3 solution via photodeposition method. The obtained amount of deposited Ag on TiO2 was in the range of 0.11 to 0.98 mass %. Deposition of Ag on TiO2 resulted in the retarding of the recombination reaction and formation of the higher amount of OH radicals on the photoc...
متن کاملPhotocatalytic self-cleaning properties of lanthanum and silver co-doped TiO2 nanocomposite on polymeric fibers
Titania, single-doped and lanthanum-silver co-doped titania nanocomposite were coated on cellulosic and polyacrylonitrile fibers via sol–gel method. The prepared samples were evaluated using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), photolumines...

متن کاملA Review of Early-Age Properties of Cement-Based Materials
Immediately after placement, gravitational forces and the local drying environment begin to influence the (micro)structure of a cement paste, mortar, or concrete. Depending on the mixture’s water-to-cementitious materials mass ratio (w/cm) (and aggregate volume fraction), the initial freshly cast material may be thought of either as a concentrated suspension of rigid particles in water or as a ...
متن کاملPhotocatalytic Self Cleaning Textile Fibers by Coaxial Electrospinning
Photocatalytic self-cleaning textile fibers have been created using coaxial electrospinning. This is accomplished by electrospinning cellulose acetate as the core phase and a dispersion of nanocrystalline TiO2, a well-known photocatalyst, in the sheath phase. A simple deacetylation step after the initial electrospinning yields self-cleaning textile fibers. Self-cleaning activity is exhibited at...
