Popis: In the paper, the EIS structure with high-k CeO 2 sensing film has more responsive to H+ relative to Na+ and K+. The CeO 2 sensing membrane annealed with O 2 at 800°C shows a higher sensitivity of 58.76 mV/pH, higher linearity, lower hysteresis voltage of 5.97 mV and lower drift rate of 0.96 mV/hr than the other conditions.
