摘要: Abstract Titanosilicate ETS-10 membranes have been prepared on porous α-alumina and stainless steel tubular supports by seeded hydrothermal synthesis. The influence of synthesis conditions has studied, pure ≈5 μm thick were synthesised, exhibiting a good intergrowth crystals. characterised X-ray diffraction, scanning electron microscopy, energy dispersive spectrometry mapping. Pervaporation experiments performed, yielding at 150 °C water/ethanol separation factor up to 12 water flux 1.1 kg/(m2 h).
