1. For organosilica membranes, one of the potential applications of separation is H2 purification at high temperatures from C3H6. But the thermal stability of organosilica membranes has remained unclear, because membranes are usually prepared and used at temperatures lower than 300 °C due to decomposition of the organic linking units at high temperatures. The development of organosilica materials-derived membranes with thermal/oxidation stability at high temperatures and high gas selectivity remains a challenge. To this end, we developed organosilica membranes prepared at high temperatures under N2 and membranes showed excellent selectivity with high levels of H2 permeance and a permeation performance that could be tailored by treatment under air at 550 °C.2. Microporous inorganic membranes prepared via a sol-gel method were proposed for O2/SO3 separation. Single-gas permeation measurements revealed that silica-zirconia membranes with a large pore size and a high Si/Zr molar ratio had good resistance to SO3, which was confirmed by the change of gas permeance. Characterizations including BET, EDS, and pH indicated the SiO2, α-Al2O3 and lower Zr-content SiZr powders had good chemical stability against SO3 even at 550 °C. In the binary-component gas separation of SO3/O2, the membrane that consisted of BTESE separation layer, SiZr (Si/Zr = 7/3) intermediate layer and α-Al2O3 support layer showed an O2 permeance of 2.5*10－8 mol m-2 s-1 Pa-1 and exhibited an O2/SO3 selectivity of 10.

1. 对于有机硅膜，分离的潜在应用之一是在高温下从 C3H6 中纯化 H2。但有机硅膜的热稳定性仍不清楚，因为由于高温下有机连接单元的分解，膜通常在低于300℃的温度下制备和使用。开发具有高温热/氧化稳定性和高气体选择性的有机硅材料衍生膜仍然是一个挑战。为此，我们开发了在 N2 下高温制备的有机硅膜，该膜表现出优异的选择性、高水平的 H2 渗透性以及可通过在 550 °C 空气下处理来定制的渗透性能。2。提出通过溶胶-凝胶法制备微孔无机膜用于 O2/SO3 分离。单一气体渗透测试表明，大孔径和高Si/Zr摩尔比的二氧化硅-氧化锆膜对SO3具有良好的抵抗力，这通过气体渗透率的变化得到证实。 BET、EDS 和 pH 等表征表明，SiO2、α-Al2O3 和较低 Zr 含量的 SiZr 粉末即使在 550 °C 下也对 SO3 具有良好的化学稳定性。在SO3/O2二元气体分离中，由BTESE分离层、SiZr(Si/Zr=7/3)中间层和α-Al2O3支撑层组成的膜的O2渗透率为2.5*10－8 mol m-2 s-1 Pa-1，O2/SO3选择性为10。
