Composition for use in a NOx electrode, method of making the same, an NOx electrode derived therefrom, and method of detecting NOx

摘要

Disclosed herein is a composition for use in a NOx electrode comprising:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Tb(1-x)Ln(x)E(1-y)Q(y1)X(y2)Z(y3)O3
wherein Ln is a lanthanoid or a combination of lanthanoids, E is a metal selected from chromium, iron, and a combination thereof, Q is an element selected from magnesium, calcium, strontium, and a combination thereof, X is an element selected from boron, lead, phosphorus, germanium, and a combination thereof, Z is an element selected from barium, silicon, aluminum, and a combination thereof, x is from 0 to about 0.5, y is from about 0.05 to about 0.8, and y1, y2, y3 are independently from 0 to about 0.8, with the proviso that y = y1 + y2 + y3, and y2 + y3 is greater than 0. Also disclosed are a method of making it, electrodes and sensors comprising it, and a method of detecting NOx.
