Abstract

Incorporation of Li cations into MOFs by either of two methods, chemical reduction or cation exchange, significantly improves the CO₂/CH ₄ selectivity. While the selectivity enhancement by the chemical reduction seems to come from favorable displacement of catenated frameworks, the selectivity improvement by the Li cation exchange comes from enhanced solid-gas interactions.
