Herein, we demonstrate the fabrication of Ti3C2Tx electrodes using solution processing. Two-dimensional (2D) nanometer Ti3C2Tx flakes are site-aggregated on copper and nickel foam papers with a reconstituted threedimensional (3D) structure consisting of overlapping and open-pore 2D flakes. When Ti3C2Tx was used as electrochemical capacitor electrodes in 1M Na2SO4 solution, the capacitances were comparable to literature values. There is a quantitative linear relationship between the capacitance and foam thicknesses. Given the process scalability and the morphological control that is possible, these results provide a promising road map for convenient and economical supercapacitors.
