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...

Photocatalytic ceramic membranes have attracted considerable attention for industrial wastewater treatment. However, morphological control of the membrane surface to improve its photocatalytic reactivity for the degradation of organic pollutants remains a challenge. Herein, we report a new nanostructured TiO2/Al2O3 composite ceramic membrane prepared from a poly(oxyethylene methacrylate) (POEM)...

Transparent photocatalytic surfaces are of ever increasing importance for many applications on self-cleaning windows and tiles in everyday applications. Here, we report the formation and photocatalytic testing of a quasi-transparent thin and nanoporous titania films deposited on glass plates. Sputtered Ti thin films were anodized in fluoride-ion-containing neutral electrolytes to form optically...

THE EFFECT OF CALCINATION TEMPERATURE TO COMPOSITECHARACTERISTICS TiO2SiO2 NANOPARTICLE. Self-cleaning material is a that utilizes the photocatalytic property to degrade organic and inorganic compounds with help of UV light. One materials have good TiO2, causes TiO2 be amphiphilic: becomes hydrophilic when there light hydrophobic no The can improved addition buffer such as SiO2. nanoparticle wa...

The prospect of nano-photocatalysts in cementitious systems is promising but the engineering application still limited, caused by insufficient insights on durability properties during service. Mortars with different binders and photocatalysts are prepared characterized to investigate deterioration mechanisms self-cleaning performance upon simultaneous hydration/carbonation. Alterations driven c...
