Abstract

Templated arrays of α-Fe2O3 nanotubes, produced using an alumina membrane, exhibit enhanced sensitivity to ethanol and hydrogen as well as enhanced electrochemical activity in lithium-ion batteries. The nanotubes, characterized by uniform size and shape (see Figure), possess a high specific surface area, leading to electrochemical activities much higher than that of bulk or nanoparticulate α-Fe2O3.
