Flame-Made Pt-Loaded TiO₂ Thin Films and Their Application as H₂ Gas Sensors

Figure 3

(a) SEM image and (b) corresponding selected area-EDS analysis of the flame-made (5/5) 0.50 mol% Pt-loaded TiO₂ films sensor on an Al₂O₃ substrate interdigitated with Au electrodes. (c) The cross-sectional sensing films were spin-coated onto Au/Al₂O₃ substrate after annealing and sensing test at 300–400°C in dry air.
