This unique compendium describes research progress on metal-organic framework (MOF) membranes for different relevant industrial gas separations. Specifically, the book focuses mainly on gas separations which are important in flue gas treatment, natural gas purification, hydrogen purification, and nuclear reprocessing. The advantages of using MOFs in mixed matrix membranes are discussed. Some of the pressing challenges in the field, and strategies to potentially overcome them are also distinctly outlined.This volume is a useful reference materials for professionals, academics, researchers and postgraduate students in chemical engineering and materials engineering.
