Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A new porous coordination polymer, ([La(BTB)H₂O]·solvent (<bold>1</bold>⊃guest)), is synthesized. Gas adsorption, ideal adsorbed solution theory (IAST) and breakthrough experiments of it exhibits high CH₄ separation capability toward CO₂ and C2 hydrocarbons at 273 K. In addition, this also shows good water and chemical stability, in particular, it is stable at pH = 14 at 100 °C, which is unprecedented for carboxylate‐based porous coordination polymers. Furthermore, the effective adsorption site for separation is revealed by using an in situ diffuse reflectance IR fourier transform (DRIFT) spectra study.</p> </abstract>
