| 中文摘要: |
| 在室温下用氢气泡动态模板阴极沉积法直接快速制备了由枝晶够成的三维多孔铂膜(3D PDPFs)。详细研究了沉积电势、温度、时间、电解质和基底等实验参数。采用扫描电子显微镜(SEM)和X射线衍射(XRD)对沉积的3D PDPFs进行了表征。3D PDPFs展现出多种能性：相对于光滑的铂电极,对甲醇氧化的电催化活性提高,吸附吡啶的表面增强拉曼散射(SERS)信号相当强,以及该3D PDPFs修饰N-十二烷硫醇单层后的表现出超疏水性。该方法为三维PDPFS的制作提供了一种简单的新方法。 |
| 英文摘要: |
| Three-dimensional porous dendritic Pt films (3D PDPFs) were prepared by cathodic deposition utilizing hydrogen bubble dynamic template at room temperature. The deposition conditions were investigated in detail including potential, temperature, time, electrolyte and substrate. The deposited PDPFs were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The 3D PDPFs displayed multifunctions like improved electrocatalytic activity toward methanol oxidation with respect to the smooth Pt electrode, fairly strong surface-enhanced Raman scattering (SERS) signals for adsorbed pyridine, and super-hydrophobicity after decorating a monolayer of n–dodecanethiol. The present method provides a new simple strategy toward the fabrication of 3D PDPFs with multiform applications. |
