Nature, Published online: 22 June 2022; doi:10.1038/d41586-022-01548-8

Membranes made from metal–organic frameworks contain modular pores that can separate mixtures of gas. By changing the shape of these pores to improve molecular separation, we produced a membrane that could remove nitrogen and carbon dioxide from natural gas in an energy-efficient and cost-effective way.
