Toward a Rational Design of Titanium Metal-Organic Frameworks

Abstract

Titanium metal-organic framework (Ti-MOF) is an unexploited area due to its unpredictable chemistry in solution and, thus, the challenge of controlling the reaction process and product. By linker exchange with a Ti8O8 cluster precursor, the first green scalable controlled synthesis of a Ti-MOF structure is achieved following both post-synthetic and one-pot reaction routes. The chemical functionality and environment of the MOF pore could be tuned easily by mixed linker, resulting in an adjustable performance in CO2 capture over N2.
