Three in One: Engineering MOF Channels via Coordinated Water Arrays for Regulated Separation of Alkanes and Alkenes

Purifying alkenes (mainly ethylene and propylene) by removing their corresponding alkanes is crucial yet challenging in the chemical industry. Selective physisorption shows promise for effective separation but demands precise pore dimensions and/or pore chemistry of adsorbents. We report an yttrium-based metal-organic framework, Y
