Abstract

A three-dimensional (3-D) metal–organic framework (MOF) with 3-D channels, named CuBTC (or called also MOF-199 or HKUST-1 {Cu₃(C₉H₃O₆)₂(H₂O)₃·xH₂O}), BTC = benzene-1,3,5-tricarboxylate was synthesized by wet chemical method. All of prepared samples were characterized by X-ray diffraction, FT-IR spectroscopy, scanning electron microscopy and BET surface area. The results indicate that CuBTC which was prepared at 110 °C having an octahedral structure and good morphology. The effect of different temperature on their properties was also investigated. Concurrently, these materials CuBTC allow the adsorption of CO using the constant volume method in the condition of my laboratory.

Keywords. Metal organic framework, CuBTC, hydrothermal, wet chemical and benzene-1,3,5-tricarboxylate.
