Multiple Construction of a Nanoporous Pillared-Layered Metal−Organic Framework with High Potential in Adsorption of CO2, H2, and N2 Gases

Abstract

Reduction of atmospheric carbon dioxide, which is one of the main components affecting global warming, and hydrogen storage as a renewable energy source by effective sorbents are considered to be vital challenges. In this work, a nanoporous pillared-layered metal−organic framework of [Zn2(TDC)2(DABCO)]·(DMF)4 (1) (TDC2− = thiophene-2,5-dicarboxylate, DABCO = 1,4-diazabicyclo[2.2.2]octane, and DMF = N,N-dimethylformamide) as a sorbent was synthesized by several methods, and its structure was determined by single-crystal X-ray analysis. Then, its physicochemical characteristics were investigated by using a set of analyses. The potential of 1 in capturing nitrogen, hydrogen, and carbon dioxide ..
