dc.description.abstract | The 0.45 mol% Ru-doped SnO2 (Ru-SnO2) hollow spheres, each with a shell thickness of similar to 17 nm, were prepared by the uniform coating of Ru- and Sn-precursors onto SiO2 microspheres with diameters of similar to 300 nm, followed by heat treatment at 350 degrees C and subsequent: removal of the core SiO2 using a dilute HF solution. The Ru-SnO2 hollow spheres showed high responses to 5 ppm trimethylamine (TMA) at 350 degrees C with negligible cross-responses to toluene. benzene, NH3, CO, H-2, and C3H8 and decreased cross-responses to C2H5OH, while undoped SnO2 hollow spheres showed similar responses to TMA and C2H5OH. The selective and sensitive detection of TMA that was achieved in Ru-doped SnO2 hollow spheres is explained in relation to the catalytic sensitization of Ru and the gas-accessible hollow morphology of the thin shell configurations.
