NO2 gas sensor fabrication through AC electrophoretic deposition from electrospun In2O3 nanoribbons

In this paper, electrospinning method was employed to fabricate polymer-ceramic composite fibers from solutions containing polyvinyl pyrrolidone (PVP) and In(NO3)(3)center dot xH(2)O. Upon firing the composite fibers at 600 degrees C, In2O3 nanoribbons with cross section around 250 nm were synthesized. Gas sensor was fabricated by deposition of In2O3 nanoribbons between the electrodes via AC electrophoretic deposition. Gas sensing measurements showed that this material has high response to very low concentrations of NO2 gas at 200 degrees C. (C) 2011 Elsevier BM. All rights reserved.
