Microporous Zirconia-Titania Composite Membranes Derived from Diethanolamine-Modified Precursors

Microporous zirconia–titania composite membranes have been fabricated by sol–gel processing using diethanolamine‐modified precursor solutions. Microporous materials made from powders calcined at 400 °C show type I nitrogen sorption behavior. Supported ∼0.1 μm thick membranes (see figure) exhibit mol...

Summary:Microporous zirconia–titania composite membranes have been fabricated by sol–gel processing using diethanolamine‐modified precursor solutions. Microporous materials made from powders calcined at 400 °C show type I nitrogen sorption behavior. Supported ∼0.1 μm thick membranes (see figure) exhibit molecular‐sieving properties and are expected to have great potential for separation and reaction applications under harsh conditions.
