| 논문초록 | The direct formation of carbon-heteroatom bonds from inert gases is essential for chemical/biological processes, energy storage systems, and electrocatalyst. However, its application to carbon nanomaterials for improved electrochemical activity remains technologically challenging. We describe a simple and very fast method to form carbon-heteroatom bonds by ultrasonic spray chemical reaction. Electrodes of nitrogen- or oxygen-doped carbon nanomaterials are fabricated via the fixation between N2 or O2 carrier gas molecules and ultrasonically activated carbon precursors. The materials exhibited much higher energy storage performances after doping. Furthermore, double nozzle system of ultrasonic spray can synthesize the mutiple heteroatom doped carbon nanomaterials, so we built-up the library and applied them into various electrochemical applications. |
