利用准二维电沉积法,通过控制不同浓度的PdCl2溶液和沉积电压,在硅衬底上制备出了钯微/纳米结构材料,分别用扫描电子显微镜和透射电子显微镜对沉积物的形貌和结构进行了表征.结果表明,随着溶液浓度和沉积电压的不同,沉积物呈现出准阵列、“树枝”状和膜状三种形貌,溶液的离子浓度和生长电势对于沉积物形貌具有决定性的影响,这些钯微/纳结构材料均由钯纳米颗粒构成,属于面心立方结构. By means of quasi-two-dimensional electrodeposition, palladium micro / nano structure materials were prepared on silicon substrate by controlling the concentration of PdCl2 solution and deposition voltage. Scanning electron microscopy (SEM) and transmission electron microscopy The results show that with the different concentrations of solution and deposition voltage, the sediments exhibit quasi-array, “branch” and film morphology, and the ion concentration and growth potential of the solution have great influence on the shape of sediment The appearance has a decisive influence and these palladium micro / nano-structured materials consist of palladium nanoparticles, which are face-centered cubic structures.
