Abstract

Indium oxide (In2O3) nanorods (NRs) which can be expected to increase the device
performance in various electronic and electrochemical applications were prepared on carbon
fibers via an electrochemical deposition (ED) method. During the ED, the indium hydroxide
(In(OH)3) NRs were well grown and firmly attached onto the carbon fibers. After that, they
were changed into In2O3 by dehydration through a thermal annealing. The morphological
and structural properties were investigated using field-emission scanning electron microscope
images. The crystallinity of as-prepared sample was evaluated by X-ray diffraction. The
Fourier transform infrared results confirm that the functional groups are present in the In2O3
NRs. This facile process of metal oxide nanostructures on carbon fiber can be utilized for
flexible electronic and energy related applications.

Keywords: Carbon fibers, In2O3 nanorods, Electrochemical deposition process
