Inorganic based membranes are promising candidates for a variety of applications, including adsorption and separation due to their large surface area, high pore volume, tunable structure, and strong resistance against aggressive operation conditions, such as high temperature and pressure. Many research groups have investigated zeolite, micro- or mesoporous silica, and hybrid materials (organic and inorganic materials) as advanced membrane configurations in liquid separation applications. Especially, hydrophobic inorganic membranes have potential to separate ethanol from aqueous solution via pervaporation, ultimately producing ethanol, but several important challenges such as reliable synthesis, fabrication, or functionalization are yet to be solved. More specifically, a novel, high throughput process for the fabrication of continuous and defect-free hydrophobic inorganic membranes is required. Then, functionalization of pore structures of the membrane, if necessary, is desirable in order to tailor even more advanced hydrophobic properties for ethanol. Finally, the separation characteristics and performance of inorganic membranes must be further investigated to implement in the industry. Herein, the synthesis and normalized separation performance of diverse hydrophobic inorganic membranes with respect to selective layer material basis, such as zeolite, functionalized mesoporous silica, and mixed matrix, are comprehensively reviewed and the future direction is presented with a focus on ethanol recovery.

无机基膜由于其大表面积、高孔体积、可调节结构以及对侵蚀性操作条件（如高温和高压）的强抵抗力而成为各种应用的有希望的候选者，包括吸附和分离。许多研究小组已经研究了沸石、微孔或中孔二氧化硅和混合材料（有机和无机材料）作为液体分离应用中的先进膜配置。特别是，疏水无机膜有可能通过全蒸发将乙醇从水溶液中分离出来，最终产生乙醇，但一些重要的挑战，如可靠的合成、制造或功能化仍有待解决。更具体地说，一部小说，需要用于制造连续且无缺陷的疏水无机膜的高通量工艺。然后，如果需要，需要对膜的孔结构进行功能化，以便为乙醇定制更先进的疏水特性。最后，必须进一步研究无机膜的分离特性和性能，以便在工业中实施。在此，对沸石、功能化介孔二氧化硅和混合基质等多种疏水无机膜的合成和标准化分离性能进行了全面综述，并提出了未来的方向，重点是乙醇回收。为了为乙醇定制更先进的疏水特性，这是理想的。最后，必须进一步研究无机膜的分离特性和性能，以便在工业中实施。在此，对沸石、功能化介孔二氧化硅和混合基质等多种疏水无机膜的合成和标准化分离性能进行了全面综述，并提出了未来的方向，重点是乙醇回收。为了为乙醇定制更先进的疏水特性，这是理想的。最后，必须进一步研究无机膜的分离特性和性能，以便在工业中实施。在此，对沸石、功能化介孔二氧化硅和混合基质等多种疏水无机膜的合成和标准化分离性能进行了全面综述，并提出了未来的方向，重点是乙醇回收。
