Review of Membranes for Hydrogen Purification

Non-renewable nature, associated pollution, and limited resources of fossilfuels, have motivated researchers and industries toward clean and renewableenergy sources. Hydrogen has emerged as a potent clean energy source withzero environmental footprints. Several petrochemical reactions producehydrogen; however, separation, and purification of hydrogen requiresadditional effort. In this review, metallic, ceramic, polymeric and carbonicmembranes used for hydrogen separation are discussed and the effects of theirphysicochemical properties, separation mechanisms, and operationalrequirements for hydrogen separation from different feedstocks areelucidated.
