Ni-doped cu-btc for direct hydroxylation of benzene to phenol

Metal Organic Frameworks (MOFs) are novel materials with vast applications such as catalysis, dye adsorption, drug retention, or gas storage.1 MOFs can retain molecules inside their microporosity or onto its surface due to its 3D structure. One of the main advantages of the MOFs is the chemical diversity present at their surface because they consist of an organic ligand and a metal center. In this case, Copper (II) acts as the metal center and benzene-1, 3, 5 tricarboxylic acid BTC as the organic ligand, to form HKUST-1 (also known as Cu-BTC or MOF-199). Despite the diversity of existing inorganic and organic parts, each MOF usually contains only one type of transition metal. However, the advantage of having two different metals brings usually new properties, for example, in the case of Cu-Ni alloys. The objective of this work is to take advantage of two different metals, namely copper and Nickel, and of the 3D structure of the MOF. Alternatively, in other words, make Ni-doping of the HKUST-1 material, verified both by experimental and theoretical technics. Moreover, finally, test the catalytic activity of this new material, in this case, the direct hydroxylation of benzene to phenol. The Ni-doped material showed to be a better catalyst than the simple HKUST-1.
