Abstract

Graphical abstract: We report a two-step room temperature protocol for functionalization of MOF-199 (HKUST-1), with gold nanoparticles. The resulted material is comprehensively characterized. We also found, that presence of gold may induce a phase transformation of MOF under microwave heating, leading to formation of [Cu2 (OH)(BTC)(H2 O)] n material with one-dimensional channels. Abstract: 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 [Cu2 (OH)(BTC)(H2 O)] n material with one-dimensional channels.
