Hydrogen is the most viable energy carrier to replace fossil fuels and achieve zero emissions, and membrane separation is an important method to obtain high-purity hydrogen gas. However, the performance of commercial polymeric membranes has limited the development of membrane separation. Two-dimensional nanomaterials have the potential to improve membrane performance.
Hydrogen (H-2) is the most viable energy carrier to replace fossil fuels and achieve zero net emission. To realize hydrogen-based society, the development of energy-efficient and high-purity H-2 production techniques is one of the key issues as currently mature H-2 purification technologies are energy-intensive. Membrane separation is an attractive option to obtain high-purity H-2 gas with low energy consumption. However, membrane separation processes are often limited by the low performance of commercial polymeric membranes despite the progress made over the last few decades. As an alternative, twodimensional nanomaterials (2DNMs) have recently drawn tremendous attention as membrane materials thanks to their unique physical and chemical properties. Herein, we seek to offer a comprehensive review of 2DNM-based membranes for H-2 gas separation. Also, we discuss the current technological challenges and provide our perspectives for future research.
