Templated arrays of α‐Fe 2 O 3 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‐Fe 2 O 3 .
