Abstract: SnO2 nanomaterials with three kinds of morphologies like nanoparticles, nanorods and SnO2-CNT nanocomposites were controllable synthesized using CNT as a template. Cataluminescence (catalytic chemiluminescence, CTL) characteristic of ethyl acetate catalyzed on nanosized SnO2 with 3 kinds of morphologies was studied. Nanostructure and BET　surface area of the SnO2 nanomaterial was very important for the CTL. A relationship between SnO2 nanomaterial with 3 kinds of morphologies and CTL of ethyl acetate was established. Three new kinds of gas sensors have been invented based on the spectrum mentioned above.

Key words: controllable fabrication, various morphologies, SnO2 nanomaterial, cataluminescence, ethyl acetate
