Abstract

Metal organic framework material based on copper and benzene–1,3,5–tricarboxylic acid (H3BTC) was synthesized by applying electric current method. The influences of applied current, NaNO3 concentration, synthesis time and hydrate process to molecular and phase structure, morphology and specific surface area were studied. When the parameters of electrodeposition changed, CuBTC one dimension (1D) and three dimensions (3D) could be obtained. The optimum conditions to gain CuBTC 3D were: 100 mA current, NaNO3 concentration of 0.05 M with synthesis time of 10 min. The short-time hydrate process could increase specific surface area from 79 m2/g to 617 m2/g, however, the long-time hydrate process could lead to the destruction of material structure.
