Introduction of macropores into an In2O3 film and simultaneous loading of CuO on the In2O3 surface were enormously effective in improving the H2S response. The large surface area of mp-In2O3 loaded with CuO, which increased the reactivity of CuO with H2S, is probably the most important factor to enhance the H2S response., 214th ECS Meeting : Honolulu, HI, October 12 - October 17, 2008, ECS Transactions, 16(11), pp.317-323; 2008@@@Chemical Sensors 8: Chemical (Gas, Ion, Bio) Sensors and Analytical Systems Editor(s): R.
