Abstract: Alcohol perm-selective pervaporations membrane could resolve the product inhibition problem effectively for the use of ethanol and butanol recovery from fermentation process. The selection and modification of membrane material，and the construction of membrane structure are the key issues for better pervaporation performance. Organic/inorganic hybrid membranes combine the advantages of both organic polymers and inorganic materials，forming highly promising membranes for separation. This paper reviews the advances in organic/inorganic hybrid alcohol perm-selective pervaporation membrane materials. Several issues and research priorities which will impact the pervaporation ability of hybrid membrane for biofuel recovery are identified and discussed，including particle structure，particle size，compatibility and dispersion of inorganic particles in the polymer，and particle loading. Novel preparation methods in recent years are also presented in detail. Finally，the prospect of developing novel particles with nano size，superhydrophobic pores and polymer compatibility are presented，and the design ideas of constructing high loading，micro- and nanoscaled hierarchical structures with high affinity to alcohol are also illustrated.
