We prepared α-Fe2O3 nanostructures assembled with nano-flakes formed through the decomposition of Fe(CO)5 and interfacial growth of nano-flakes. The time-dependent flake growth was observed and their shape and characterization of materials were determined by SEM, TEM and XRD. AAO-templated iron tubes were also formed through the decomposition of Fe(CO)5 and interfacial growth. The electrochemical behavior of iron nano-structured materials for electrode of capacitor was tested and compared over different sized nano-flakes, nanotubes, and conventional nanoparticles. Thus, α-Fe2O3 plates assembled with nano-flakes of 30 nm thickness gave an optimal result that specific capacitance was up to 171 Fg-1 and lowest capacitance decrease at high current density which showed better performance than conventional nanoparticles. These results imply that specific structure of α-Fe2O3 demonstrated by this work might be a solution which improves a performance from inherent low conducting problem. In addition, conducting polymer, polyaniline(PANI) could be composited with iron nano-structures to improve conductivity and capacity. In this work, the composited structures of PANI and iron nano-structures were demonstrated and their electrochemical behavior was investigated.
