Microbial contamination of the surface building materials and subsequent release microbial particles into air can significantly affect indoor quality. Avoiding development or, at least, reducing quantity microorganisms growing on is a key point to reduce health risks for occupiers. In that context, antimicrobial activity TiO2, ZnO Au/ZnO was assessed by measuring log reductions Escherichia coli Aspergillus niger populations both in dark under light intensity close real-life conditions. The...
Self-cleaning products are commercially available to protect surfaces against soiling and avoid the high consumption of energy chemical detergents necessary for cleaning. They based on semiconductor oxides, mostly titanium dioxide (TiO2), which induce photocatalytic oxidation activity superhydrophilicity. Therefore, we present an experimental procedure at a lab scale assess self-cleaning ability various coatings (five TiO2-based commercial one lab-grade zinc oxide (ZnO) product) applied...
WO3 is a known photocatalytic metal oxide frequently studied for its depollution properties. However, it suffers from high recombination rate of the photogenerated electron/holes pair that detrimental to performance. In this paper, we present new chemical method decorate nanoleaves (NLs) with complementary (ZnWO4) in order improve performance composite material abatement 400 ppb NO2 under mild UV exposure. Our strategy was synthesize WO3·2H2O nanoleaves, then, expose them, water-free organic...
The nanometer size Cu2O@WO3·H2O composite material has been prepared by the direct hydrolysis of mesitylcopper (I) on WO3·2H2O nanoleaves. synthesis performed in toluene without addition any ancillary ligands. nanocomposite deposited as a gas-sensitive layer miniaturized silicon devices and heated up gradually to 500 °C ambient air. During heating, CuWO4 phase is formed upon reaction Cu2O with WO3 support revealed XRD analyses. as-prepared CuWO4@WO3 sensors have exposed 10 ppm CO or 0.4 NO2...
NASICON-structured glass–ceramics based on the Li1+xCrxGeTi1–x (PO4)3 (0 ≤ x 1) system are synthesized by melt-quenching method followed glass crystallization. Since Ti4+ and Cr3+ have approximately same crystal radius in octahedral coordination, this aliovalent substitution should avoid considerable changes cell volume, thus allowing us to evaluate true contribution of a tetravalent cation trivalent one other structural factors. The structure these is investigated X-ray high-resolution...
