Oxygen permeable ceramic hollow fiber perovskite membranes could be applied as the micro-membrane reactors for high temperature oxidations to integrate air separation and reaction in same unit. Membrane reactors normally require the loading of extra catalyst. However, how to anchor the catalysts in these hollow fiber structured reactors along the surface is a big issue. In this work, the synthesis and properties of La_0.6Sr_0.4Co_0.2Fe_0.8O_3-δ (LSCF) hollow fiber perovskite membranes with wrinkled surface was reported. This article demonstrates its applicability for oxygen separation from air, before and after Ag deposition as the catalyst in the wrinkles of the hollow fibers. The wrinkled membranes display the oxygen permeation flux of 0.62 (prior to Ag deposition) and 1.48 (after Ag loading) mL·min⁻¹·cm⁻² operated at 950 °C, which is 1.2 and 3.0 times the permeation flux of membranes without wrinkles, respectively. This research contributes a novel inorganic hollow fiber membrane with wrinkled surfaces as the catalyst bed for industrial applications.

透氧的陶瓷中空纤维钙钛矿膜可以用作高温氧化的微膜反应器，将空气分离和反应集成在同一单元中。膜反应器通常需要装载额外的催化剂。然而，如何沿着表面将催化剂锚固在这些中空纤维结构的反应器中是一个大问题。La _0.6 Sr _0.4 Co _0.2 Fe _0.8 O3 _-δ的合成与性能（LSCF）具有皱纹表面的中空纤维钙钛矿膜的报道。本文证明了其在中空纤维褶皱中作为催化剂沉积Ag之前和之后从空气中分离氧气的适用性。褶皱的膜在950°C的条件下显示的氧气渗透通量为0.62（在Ag沉积之前）和1.48（Ag加载后）mL·min ^-1 ·cm ^-2，这是不使用氧气时膜渗透通量的1.2和3.0倍皱纹分别。该研究贡献了一种新型的具有皱纹表面的无机中空纤维膜作为工业应用的催化剂床。
