Abstract
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.
