Abstract

The invention relates to an YSZ based mixed-potential type acetone sensor taking NiNb206 as a sensitive electrode and a preparation method. The YSZ based mixed-potential type acetone sensor taking NiNb206 as the sensitive electrode is mainly used for detecting atmospheric environment and diabetes mellitus. The sensor comprises a Al2O3 ceramic plate with a Pt heating electrode, a YSZ base plate, a Pt reference electrode and a NiNb206 sensitive electrode in turn, wherein the reference electrode and the sensitive electrode are independent from each other and are symmetrically prepared at the two ends of the upper surface of the YSZ base plate, and the lower surface of the YSZ base plate is adhered to the Al2O3 ceramic plate with the Pt heating electrode. According to the YSZ based mixed-potential type acetone sensor taking NiNb206 as the sensitive electrode, the YSZ is served as an ionic conductive layer, the NiNb206 with high electrochemical catalytic activity is served as the sensitive electrode, and the change in microstructure of the sensitive electrode layer is realized through different calcining temperature (at 800-1200 DEG C), so that the purpose of increasing the sensitivity is achieved.

Description

technical field

[0001] The invention belongs to the technical field of gas sensors, in particular to a NiNb 2 o 6 A YSZ-based mixed potential type acetone sensor which is a sensitive electrode and a preparation method thereof are mainly used for the detection of atmospheric environment and diabetes. Background technique

[0002] Acetone, as an organic solvent commonly used in laboratory and industrial production, has been widely used in dissolving plastic products, material purification and pharmaceutical industry. Inhalation of high concentrations of acetone can cause headaches, fatigue, and even coma symptoms, which seriously damage the nervous system of the human body. It is very necessary to detect high concentration of acetone gas in the workplace and the environment. In addition, clinical medicine shows that acetone can be produced in diabetics, and the concentration of acetone in the breath of patients is significantly higher than that of normal people. The concent...
