Figure shows the cyclic voltammograms for a CNT film (panel c) and for the Cu-triazole MOF embedded in a CNT (MOF@CNT) film (panel d), measured at scan rates ranging from 0.001 to 1.0 Vs -1 in the bias range of -1.2 to 1.0 V, using a platinum wire as counter electrode, and a silver wire as reference electrode in 0.1 M of OMIM-Cl in acetonitrile as electrolyte.
