Flow-through configuration for electrochemical disinfection is considered as a promising approach to minimize the formation of toxic byproducts and energy consumption via enhanced convective mass transport compared with conventional flow-by one. Under this hydrodynamic condition, it essential ascertain effect sequential electro-redox processes cathode/anode then anode/cathode arrangements on performance. Here, carbon fiber felt (CFF) was utilized construct two flow-through electrode systems...
Abstract The high-temperature proton exchange membrane fuel cell (HT-PEMFC) offers several advantages, such as high conductivity, CO tolerance, good chemical/thermal stability, mechanical properties, and low cost. (PEM) is the critical component of HT-PEMFC. This work discusses methods current PEMs development for HT-PEMFC including modifications Nafion® membranes advancement in composite based on non-fluorinated polymers. modified Nafion®-based can be used at temperatures up to 140 °C....
The recent progress in the development of membrane materials expands applications and requirements for new, more stable, highly effective separation materials. One most interesting research directions is related to membranes containing metal–organic frameworks (MOFs), covalent organic (COFs) either matrix or inside surface. addition these (macro)molecules makes it possible tune first material properties resistance then transport features, finally improving performance significantly. This...
Zirconium dioxide membranes (3 nm and 200 nm) were chemically modified by silane-based modifiers with different degrees of fluorination. Comprehensive material characterization has been performed before after the modification process goniometric, microscopic techniques. Wetting properties accomplished applying Zisman method, Kao diagram, spreading pressure, critical surface tension. The mechanical, tribological, separation features all investigated as a function grafting time for 5h, 15h,...
Membrane separation technology can used to capture carbon dioxide from flue gas. However, plenty of research has been focused on the flat sheet mixed matrix membrane rather than thin film hollow fiber membranes. In this work, membranes were fabricated by incorporating amine functionalized UiO-66 nanoparticles into Pebax® 2533 selective layer polypropylene (PP) supports via dip-coating process. The attenuated total reflection-Fourier transform infrared (ATR-FTIR), scanning electron microscope...
Novel heterogeneous membranes based on poly(ether block amide) and poly(dimethylsiloxane) were prepared modified by incorporating the grafted alumina oxides into polymer matrix. Membranes subsequently used for separation of organic solvent mixtures (ethyl acetate/ethanol ethyl acetate/isopropanol). There four types grafting compounds applied in this research: octyltriethoxysilane (C6), 1H,1H,2H,2H-perfluorooctyltriethoxysilane (FC6), tetradecyltriethoxysilane (C12),...
