多孔Au泡沫的制备及应用

Preparation of Porous Au foam Film and Their Application

采用氢气泡模板法制备的三维多孔Au泡沫膜具有分级多孔的结构,孔壁连通,孔壁是由大量的枝晶构成。采用扫描电镜对多孔结构进行了表征。由于这种特殊的多孔结构,三维多孔Au泡沫对无酶葡糖糖传感具有较高的催化活性,为Au纳米材料在电催化领域的应用提供了更多的支持。

Au foam films with three-dimensional(3 D) hierarchical pores consisting of interconnected dendrite walls were successfully fabricated by a strategy of cathodic deposition utilizing the hydrogen bubble dynamic template.The foam films were characterized by scanning electron microscopy(SEM).Due to the special porous structure,the Au foam films show superior electrocatalytic activity toward the enzyme-free detection of glucose without interference.These findings provide more insights into the Au nanomaterials for electrocatalytic applications.
