Popis: Supported inorganic membranes hold the promise of highly effective separation and purification, and stable operation in harsh environments. Examples are thin films of paladium alloy for H2, mixed conducting oxides for O2, amorphous silica for CO2 and zeolites for hydro-carbons, and meso-porous titania for water purification. However, compared to organic membranes, large-scale production of inorganic membranes requires improvements in reproducibility and cost processes. This short overview provides terminology, concepts, and important criteria for performance, stability, reproducibility, and cost of supported inorganic membranes. Also discussed are possible approaches to address the challenges, and examples for designing gas separation and water purification.
