| 摘 要： | 本文采用团簇束流沉积方法制备了一种复合纳米粒子电化学催化剂,在碳纳米粒子支撑层上沉积钯纳米粒子薄膜,发现其在双氧水电化学传感中具有较高的灵敏度.碳纳米粒子的覆盖率对钯纳米粒子薄膜的双氧水电化学催化活性有明显的影响.当碳纳米粒子覆盖满一个单层的时候,钯/碳纳米粒子复合薄膜对双氧水的检测灵敏度达到了最高值,是没有碳纳米粒子支撑层时的两倍之多.

| Abstract: | A nanocomposite electrocatalyst was prepared with the method of cluster beam deposition of palladium nanoparticle thin lms on carbon nanoparticle supporting layers and used as sensitive nonenzyme hydrogen peroxide sensors. An enhancement on the electrocatalytic activity of the palladium nanoparticles toward H2O2 reduction was observed, which was related to the coverage of the carbon nanoparticles. With one monolayer of carbon nanoparticles, the H2O2 detection sensitivity reached the maximum, which was more than twice of that of the pure Pd nanoparticles. |
