Palladium and Carbon Membranes for Hydrogen Separation and Purification
This research community develops selective membranes and membrane reactors designed to isolate hydrogen from mixed gas streams, purify it for fuel cells, and separate hydrogen isotopes for nuclear applications.
The work centers on two primary material systems: palladium-based metallic membranes and carbon molecular sieve membranes. Recurring methods include the fabrication of composite and hollow-fiber structures, the engineering of ultramicroporous channels for precise molecular cutoff, and the integration of membranes into steam reforming and catalytic exchange processes. Applications range from extracting hydrogen from natural gas and methane to isolating deuterium and tritium. The community also investigates the enhancement of gas perm-selectivity through mixed matrix composites and the removal of carbon dioxide from hydrogen-rich streams.
The community is most heavily represented in research tracked for Palladium, accounting for 3.4% of all Palladium research and comprising 1,844 papers. It also contributes to research tracked for Hydrogen (898 papers) and Platinum (188 papers).
The community comprises 4,728 papers, published predominantly in the International Journal of Hydrogen Energy, the Journal of Membrane Science, and Fusion Technology.
Recent work continues to focus on enhancing the performance of carbon molecular sieve membranes through cross-linking and co-pyrolysis techniques, as well as optimizing palladium-alloy membranes for improved hydrogen permeability and isotope separation efficiency.
