The hybrid organic-inorganic membrane according to the present invention may comprise an amorphous porous layer incorporating organic functionalities. The amorphous porous layer may be deposited on a porous alumina substrate by chemical vapor deposition (CVD). The amorphous porous layer may comprise a single top-layer (STL), multiple top-layers (MTL) or mixed top-layers (XTL). The substrate may comprise a single layer or multiple graded layers of alumina.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/94/388/079/0.pdf12039664210/490210/500.21210/500.28210/640427/248.1427/255.23427/255.28427/255.655/52455/DIG596/1196/496/796/1296/1396/1496/4596/5196/55B01D69/141B01D53/228B01D67/0072B01D67/0079B01D2323/08Y02C10/10Y02C20/20Y10S55/05Y10T428/249957938894
