提出了一种有机-无机相结合的新型支撑膜制备方法，即在多孔的α-Al_2O_3中空纤维表面直接涂覆均匀厚度为5 mm、无缺陷的薄层Pd膜，同时膜与基材之间存在较小的间隙，使膜具有较高的氢渗透率、无限的选择性和较好的膜稳定性。
A novel combined organic and inorganic process for preparing thin supported membrane was developed, using which a thin and defect-free Pd membrane with uniform thickness of 5 mm was directly coated onto porous alpha-Al2O3 hollow fiber without any interlayer and substrate penetration; at the same time, there existed a small interstice between membrane and substrate, which led to higher hydrogen permeance, infinite selectivity, and better membrane stability.
