Non-covalent functionalization of 2,5-dimethoxy-1,4-benzoquinone and hydroquinone on reduced graphene oxide sheets led to the formation of a redox-active three-dimensional gel architecture via a one-step hydrothermal method, where the former exhibited high gravimetric and volumetric capacitance and 99% capacitance retention after 25 000 cycles at 50 mV s−1.
