MIEC Hollow-Fibre Membranes in a Plasma Membrane Reactor

: Mixed ion and electron conducting (MIEC) perovskites can be used to separate oxygen from other gases in a highly selective manner. MIEC hollow-fibre membranes can be easily manufactured and scaled up using wet spinning. Such membranes have a very high oxygen permeance due to their thin walls and high specific surface area. These membranes can be used in a plasma membrane reactor to separate oxygen after splitting of CO 2 into CO and O 2 , thereby avoiding a back reaction to CO 2 .
