Integrating ceramic based membranes into industrial separation processes has many advantages including high temperature operation, thus reducing the need to cool down gases and improving overall process efficiency. In the gas separation field, ceramic membranes can process gas streams containing hydrogen or oxygen, which are two major world commodities for petrochemical and energy applications. Hydrogen can be separated by metal oxide silica derived membranes, a molecular diffusion-controlled process. Oxygen can be separated by dense perovskite membranes, where the diffusion of oxygen ions increases by doping the ceramic crystal cubic structure. Ceramic-carbon based membranes are now closing the performance gap in desalination applications, whilst vacuum can be used to tailor the pore size of carbon embedded into the ceramic pores. In addition, novel percrystallisation membranes can be prepared by using bio-inspired carbon precursors coated on porous alumina substrates to process mineral salts, food and pharmaceutical compounds. This work presents the latest development in ceramic based membranes including a discussion on future challenges.
