Abstract

Porous anodic alumina oxide (AAO) obtained via two-step anodization is a material commonly used as a template for fabricating 1D nanostructures. In this work, copper and cobalt-iron 1D nanocones were obtained by an electrodeposition method using AAO templates. The templates were produced using two-step anodization in HCO. The Co-Fe nanostructures are characterized by homogeneous pore distribution. The electrocatalytic activity of the produced nanomaterials was determined in 1 M NaOH using the linear sweep voltammetry (LSV) and chronopotentiometry (CP) methods. These materials can be used as catalysts in the water-splitting reaction. The sample's active surface area was calculated and compared with bulk materials.

摘要

通过两步阳极氧化法制备的多孔阳极氧化铝（AAO）是一种常用的制备一维纳米结构的模板材料。在本工作中，采用AAO模板通过电沉积法制备了铜和钴铁一维纳米锥。模板是在HCO中通过两步阳极氧化法制备的。钴铁纳米结构的特征是孔径分布均匀。采用线性扫描伏安法（LSV）和计时电位法（CP）在1 M NaOH中测定了所制备纳米材料的电催化活性。这些材料可用作水分解反应的催化剂。计算了样品的活性表面积并与块状材料进行了比较。
