MOF-Derived Carbon Supported Copper Composite as Heterogeneous Catalyst
The high energy copper metal-organic framework (MOF), denoted as CuNbO-1, was used as both sacrificial template and copper source to obtain finely distributed copper particles throughout an anisotropic carbon matrix (Cu@C) via a simple decomposition at 250 °C under inert atmosphere. The Cu@C material was <3 nm in diameter composed of ~27 wt.% of copper with carbon composite. The material was applied as a heterogeneous catalyst to aerobic alcohol oxidation and reduction of nitrobenzene and compared against the previously known copper composite catalysts derived from MOFs. Furthermore, the catalytic activity of Cu@C was measured in cross-coupling reactions between iodobenzene and imidazole with moderate yields and turnover number. In all reactions, the prepared Cu@C catalyst showed comparable or higher activity, which we expect to be due to the high dispersion of accessible catalytic copper nanoparticles on the carbon matrix.
