Abstract

Microwave-assisted hydrothermal (MAH) route has been demonstrated as a powerful method for rapid synthesis of RuO₂·x H₂ O-TiO₂ nanocomposites with ideal capacitive behavior. From high resolution transmission electron microscopic and element mapping images, anatase TiO₂ crystallites are formed before RuO₂·x H ₂O nucleation under the MAH environment, enhancing the exposure and utilization of RuO₂ ·x H₂O. RuO₂-based specific capacitance reaches the maximum, 992 F g^-1 estimated from cyclic voltammetries measured at 100 mV s^-1, when 60 RuO ₂·x H₂O-40 TiO₂ is annealed in air at 150°C for 2 h, achieving the high power and high capacitance purposes.
