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‐NH 2 ) via the amide bond. The hybrid GA@UiO‐66‐NH 2 acts as an effective charge‐storing material with a remarkable capacitance. They construct an asymmetric supercapacitor (ASC) using GA@UiO‐66‐NH 2 as the positive electrode, with Ti 3 C 2 T x MXene as negative electrode.
