The structural properties of the composite gels were characterized via a thermogravimetric study (TG), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and N 2  adsorption analysis; and the optimized calcination atmosphere and temperature conditions for a microporous membrane were examined. A crack-free thin (50 nm) TiO 2 –ZrO 2 –organic layer for gas separation was formed on a SiO 2 –ZrO 2  intermediate layer (150 nm) supported on a macroporous α-Al 2 O 3  substrate as an asymmetric membrane. Compared with DEA, more of the ISOH and its remnants effectively remained after calcination, which promoted higher permeance and selectivity as a microporous gas separation membrane by forming bimodal microporous structures that narrowed the original TiO 2 –ZrO 2  pores. A TiO 2 –ZrO 2  membrane with ISOH calcined at 350 °C under a N 2  atmosphere showed He and CO 2  permeances of 1.0×10 −6  and 2.0×10 −7  mol m −2  s −1  Pa −1 , respectively, at 200 °C. The CO 2 /N 2  permeance ratio was 6.4 at 200 °C and 46 at 35 °C."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004232369201796","@type":"Researcher","foaf:name":[{"@value":"Toshiya
