High Working Capacity Acetylene Storage at Ambient Temperature Enabled by a Switching Adsorbent Layered Material.

ABSTRACT: Unlike most gases, acetylene storage is a challenge because of its inherent pressure sensitivity. Herein, a square lattice (sql) coordination network [Cu(4,4'-bipyridine)₂(BF₄)₂]_n (sql-1-Cu-BF₄) is investigated with respect to its C₂H₂ sorption behavior from 189 to 298 K. The C₂H₂ sorption studies revealed that sql-1-Cu-BF₄ exhibits multistep isotherms that are temperature-dependent and consistent with the transformation from "closed" (nonporous) to four "open" (porous) phases induced by the C₂H₂ uptake. The Clausius-Clapeyron equation was used to calculate the performance of sql-1-Cu-BF₄ for C
