<P>Pure In2O3 and In2O3/Co3O4 composite nanoparticles were synthesized by a hydrothermal process using indium acetate and cobalt acetate as precursors. The In2O3/Co3O4 composite nanoparticles provided enhanced sensing performance. In particular, the responses of the pure In2O3 and In2O3/Co3O4 composite nanoparticle sensors to 200-ppm acetone at 250 degrees C were 5.55 and 15.54, respectively. The response and recovery times of the pure In2O3 sensors to 200-ppm acetone at 250 degrees C were 7 and 30 s, respectively, whereas those of the In2O3/Co3O4 composite nanoparticle sensor were 2.5 and 18 s, respectively. The underlying mechanism for the improved sensing characteristics of the In2O3/Co3O4 sensor were also discussed.</P>
