Yttrium-stabilized zirconia-based electrochemical gas sensors have good application prospects in NO high-temperature detection systems due to their stability under extreme conditions. In this study, an LaMO3 (M: Cr, Mn, Fe, Co, and Ni) perovskite was prepared using the sol–gel method as the electrode material for an yttrium-stabilized zirconia-based electrochemical sensor for the selective detection of NO. The influence of M-site metals on the electrode performance was revealed through various experimental characterization studies and first-principles calculations. The results indicate that the response values of the different M-site metal perovskites can be arranged in the following order: LaCrO3 > LaMnO3 > LaFeO3 > LaNiO3 > LaCoO3. Among them, LaCrO3 exhibits a response value of −64.11 mV to 100 ppm NO, with high sensitivity (−41.19 mV per decade) and high selectivity. Further research has demonstrated that the number of oxygen vacancies and response values in these perovskite materials follow the same order. Electrochemical impedance spectroscopy indicated that LaCrO3 exhibited the lowest polarization resistance, and that these changes promoted the adsorption and reaction of NO on the electrode. Finally, the mechanism of NO adsorption on the LaCrO3 surface was revealed using density functional theory calculations. This study not only provides a new approach for selecting high-performance electrode materials but also reveals the fundamental impact of M-site metals on the performance of perovskites.

Framing effects are a phenomenon where individuals respond differently to equivalent information presented in a positive or negative manner. Whether framing effects within audit evidence affect auditor judgment is unknown. We conduct a simulated client inquiry experiment to investigate whether the framing of an inquiry evidence item (positive versus negative) and the timing of the frame within the inquiry evidence series (at the beginning versus end) influences auditor judgment. More consistent with attribute framing than belief-adjustment predictions, our findings suggest a primacy effect where participants who receive a positive frame at the beginning of the inquiry are less likely to change their initial assessments of misstatement than participants who receive a "neutral" perspective (i.e., both positive and negative frames simultaneously). Our results imply that positively framed initial evidence, relative to other settings, may constrain auditors' consideration of subsequent evidence when making judgments about the account in question.
