A facile composite of tremella-on-sheet manganese dioxide (MnO2)/titanium dioxide (TiO2) has been fabricated successfully as the electrode material for supercapacitors. The results of scanning electron microscopy and transmission electron microscopy reveal that hierarchical tremella-like MnO2 grows onto the exfoliated two-dimensional (2D) TiO2 nanosheets. The uniquely structured composite covers a large specific surface area with typical mesoporous characteristics for achieving high pseudocapacitance performance. The composite exhibits higher specific capacitance (286.69 F g(-1) at a current of 1 A g(-1)) and has 81.1% retained specific capacitance after 1000 cycles in three-electrode system. The high performance of the electrode is attributed to a unique structure, 3D hierarchical morphology, particular conductive substrate, and low contact resistance. (C) 2015 Elsevier Ltd.
