Figure 9.

Simulated response of the sensor decorated with TiO₂ to NO₂ as a function of the NO₂ concentration according to the selected temperature profile (shown in Figure 8). ×-blue markers: Results obtained by sampling the sensor response at the end of the last T_high pulse of each NO₂ injection phase. O-blue markers: Results obtained by sampling the sensor response at the end of the last T_low pulse of each NO₂ injection phase, as shown in Figure 8. Red and black lines are the responses obtained at the end of each $N{O}_2$ injection phase at a constant temperature as per legend.
