Discriminating hazardous gas mixture via a zirconia-based amperometric gas sensor

A Highly Sensitive and Selective NH3 Sensor Based on a Spherical In2O3-Sensing Electrode Prepared Using the Hydrothermal Method

“…After that, the MnO 2 layer was cooled down to room temperature at a rate of 3 °C min −1 to form the manganese-based reference electrode (Mn-based RE). [33][34][35] The In 2 O 3 powder prepared above and the α-terpineol were thoroughly mixed to obtain a screenprinting slurry. These slurries were screen printed on the other side of the YSZ plates that were attached with pre-sintered Mn-based REs to form sensing electrodes (SEs).…”

Facile synthesis of zirconia-coated mesoporous silica particles by hydrothermal strategy under low potential of hydrogen conditions and functionalization with dodecylphosphonic acid for high-performance liquid chromatography

“…Over the past few decades, zirconium dioxide (zirconia), owing to its high mechanical strength and good chemical stability over a wide pH range of 1-14 [ 1 , 2 ] has triggered increasing academic interest as a sorbent for gas sensors [3] , catalysis [4] , sample pretreatment [5] and chromatographic separation [6] . However, zirconia microspheres show drawbacks of a low specific surface area ( < 100 m 2 g −1 ) [2] and undesirable pore structure [7] , which often limit their applications.…”
