Description
Summary:In article number 2004560, Kolleboyina Jayaramulu, Deepak Dubal, Radek Zboril, Roland A. Fischer, and co‐workers report covalent attachment of graphene acid (GA) and an amine‐functionalized metal–organic framework (UiO‐66‐NH2) via the amide bond. The hybrid GA@UiO‐66‐NH2 acts as an effective charge‐storing material with a remarkable capacitance. They construct an asymmetric supercapacitor (ASC) using GA@UiO‐66‐NH2 as the positive electrode, with Ti3C2Tx MXene as negative electrode.
