“…In general, the HCs sensitivity has been reported to be enhanced with increasing carbon number within the same HCs group, as illustrated in Fig. 13 [51,58,105,107,108,110,112,[114][115][116][117][118][119][120][121][122][123]. Additionally, it was also reported by Hibino et al that HCs sensitivity increased with the order of alkane, alkene, and alkyne in the case of same carbon number (Fig.…”

“…However, other SE materials with a lower melting point such as Au need to be stabilized by using a different approach. Figure 12a, b represents SEM images of Au-SEs before and after the sensor operation for 57 days, as reported by Elumalai et al [117]. It was observed that Au particles were agglomerated and formed monolithic-like layer after the long-term operation at high temperatures.…”

“…However, isolated Au particles appeared to be stabilized even after 2 months of operation by using NiO as an alternative base component of the SE (NiO, 95 wt% and Au, 5 wt%), as presented in Fig. 12c, d [117]. As a result, the sensor has maintained good stability toward C 3 H 6 sensing.…”

A robust and reliable gas sensing device is considered as a convenient and practical solution for gas concentration monitoring that has become a mandatory requirement in different field of applications. For in situ hazardous gases detection, a mixed-potential type gas sensor has been regarded as a promising solid-state gas sensor. For the past three decades, there has been a significant progress in achieving high performance in mixed-potential type sensors. Therefore, this review is focused on reporting the development of mixedpotential type gas sensors with combined yttria-stabilized zirconia (YSZ) as the base solid electrolyte material and various classes of electrode materials for their potential utilization as a high-performance sensing electrode. The underlying sensing mechanism of a mixed-potential type YSZ-based sensor is elaborated here in detail. Transformation in design and configuration of this type of sensor is also covered in this report. In addition, recent progresses on mixed-potential type gas sensors development for detection of several target gases, such as carbon monoxide, hydrocarbons, nitrogen oxides, hydrogen, and ammonia, are reviewed. Strategies to improve the sensing characteristic, particularly gas sensitivity and selectivity, are also reported. Based on the understanding of the fundamental sensing mechanism and the requirements for high-performance gas sensors, challenges and future trends for this type of gas sensor development are discussed.

“…Based on these facts, we have considered that ZrSiO 4 is one of potential candidates to function as a base SE material for a YSZ-based gas sensor. Meanwhile, Au has been championed as a component of attractive composites, since the gas sensors using each of composite materials (oxide+Au) as SE have been reported to give a desirable sensing characteristic [14][15][16].…”

“…On one hand, the composition of the sensing electrode materials plays an important role on the sensing property of the mixed potential type NO x sensor based on YSZ. The oxide sensing electrodes such as NiO have been testified to have high electrochemical catalytic activity to NO x [12][13][14][15][16][17][18][19][20]28]. On the other hand, the TPB is the reaction field where the electrochemical reactions take place.…”
