(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.
