Polypropylene-based aerogels with high surface area have been developed for the first time. By chemical crosslinking of polypropylene oligomeric capped-end amino compounds, followed by dissolution, thermally induced phase separation, and supercritical CO2 drying process or freeze-drying method, exhibit specific areas up to 200 m2/g. Moreover, silica-cage multi-amino compound was utilized in a similar vein forming hybrid aerogels. According SEM, polypropylene-based highly porous morphology...
Up to now, the research has been mostly devoted photocatalytic removal of individual pollutants. As in real situations, pollutants are always presented a mixture, it is crucial know whether there some sort interference, which can influence efficiency whole degradation process. Here, we investigated ability two commercial coatings (binder-containing FN NANO®2 and binder-free AEROXIDE® TiO2 P25) abate ozone, nitric oxide, acetaldehyde separately their mixtures. Both photocatalysts effectively...
In the literature, abatement of nitrogen oxide (NOx) emissions by photocatalysis is rarely carried out at real-world air flow velocities. Here, we investigated performance two commercial photocatalysts, Aeroxide® TiO 2 P25 (Evonik Industries, Germany) and FN NANO®2 (Advanced Materials-JTJ, Czech Republic), containing 88 % anatase 12 rutile, while moreover 13 a binder. The degradation NOx pollutants (0.1 1.0 ppmv) velocities ranging from 0.02 to 0.7 m s−1 was tested, photocatalytic efficiency...
Abstract g-C 3 N 4 layers with good mechanical properties, including their cohesion and adhesion to stainless-steel supports, were prepared by the quantitative electrophoretic co-deposition of WO nanocrystals. It was carried out in a mixture organic solvents applying voltage 750 V. The typical layer area density 0.64 mg cm –2 . photocatalytic degradation 4-chlorophenol under blue-light irradiation showed that performance stable composite containing 25–50 wt.% only slightly weaker than...
Traditional wastewater treatment often fails to remove pharmaceuticals, necessitating advanced solutions, such as TiO
The ISO standard 22197-1:2016 used for the evaluation of photocatalytic nitric oxide removal has a main drawback, which allows only decrease to be determined specifically. remaining amount, expressed as “NO2”, is considered sum HNO3, HONO NO2, and other nitrogen-containing species, can potentially formed during reaction. Therefore, we developed new methodology combining our custom-made analyzers, accurately determine true NO2 with conventional NO one. Their function was validated via...
The variability of the nanostructure carbon materials results in a uniquely wide range physical and chemical properties. In this work, we studied how affects thermal stability 2D 3D graphene-based (graphene, fullerene, nanotubes, zeolite-templated carbon), disordered ordered mesoporous (activated carbons, CMK-3, 3DOMM), layered (few-layer graphene, graphene nanoplatelets, graphite) air. combination structural, thermogravimetric calorimetric analysis under identical conditions for all...
