文摘
We report the self-assembly of microsized nanowalls and nano-/micropatterns of magnetic iron oxidesupon the oxidation of electrodeposited Fe-based films when annealed in air at temperatures ranging from300 to 450 
C. Scanning electron microscope studies indicate that these nanowalls have the thinnest wallof down to ~8 nm with a length up to ~2 
m and a height reaching ~6 m; the square patterns havean area of 0.06-1.0 m2. The generated nanowalls can be used to detect O2 or H2 at high temperaturesvia their resistance change. The simple spontaneous synthesizing procedure reported here can be appliedas well to other electro-/electroless-deposited metal films to form zero-, one-, and two-dimensional metal-based nanostructures.
