A room-temperature growth of gold nanoparticles on MOF-199 and its transformation into the [Cu-2(OH)(BTC)(H2O)](n) phase

We report a two-step room temperature protocol for functionalization of copper-based metal-organic framework MOF-199, also known as HKUST-1, with gold nanoparticles. The resulted material is characterized with XRD, TEM, BET, UV-Vis and FTIR techniques building up a complete picture of its structural, electronic and vibrational properties. We also found, that the presence of gold induces a partial phase transformation of MOF under microwave heating, leading to formation of [Cu-2(OH)(BTC)(H2O)](n) material with one-dimensional channels.
