摘要：

We prepared crystalline Ag nanocluster-incorporated RuO(2) electrodes using a radio frequency magnetron cosputtering system for use in thin-film micropseudocapacitors and investigated their structural and electrochemical properties. High-resolution electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy results show that crystalline Ag nanoclusters are well dispersed within an amorphous RuO(2). The Ag nanocluster-incorporated RuO(2) electrodes show much higher capacitance of similar to 1306.0 F/cm(3) at 200 mV/s with superb high-rate performance compared to RuO(2)-only electrodes. The improved capacitance is explained in terms of the presence of dispersed Ag nanoclusters embedded within the amorphous RuO(2) matrix having good electrical conductivity.
