Abstract:A simple and fast route for the synthesis of metal-organic framework(MOF) particles was presented. Cu-3(BTC)(2)(HKUST-1, BTC=1,3,5-benzenetricarboxylate), one of the most well-known MOFs, was synthesized at room temperature via coordination modulation method. By adding different modulators(monocarboxylic acids) into the reaction system, the morphologies of HKUST-1 crystals were tuned from nano spheres to micro octahedrons at room temperature without any complex equipment. X-Ray diffractions and gas sorption measurements revealed highly crystalline particles with large Brunauer-Emmett-Teller(BET) surface areas(1116-1273 m(2)/g) and total pore volumes(0.62-0.73 cm(3)/g). The significantly small particle sizes and high capacity of gas sorption are considered advantageous for envisaged application in practical industrial process.
