Highly sensitive gas sensors are realized from Uniformly loaded Pt@SnO2 nanorods, which are synthesized via one-step hydrothermal routes. At 300 degrees C, the sensitivity of the sensors upon exposure to 200 ppm ethanol is up to 39.5. Such a high gas sensing call be attributed to both the chemical and the electrical contribution of Pt. Interestingly, at 200 degrees C, the response of the sensors is characterized by opposite variations of resistances, which probably arise from temperature-dependent forms of surface oxygen ions. The present results demonstrate an available direction for realizing high-performance gas sensors.
