Nanoscale ceramic materials for power-efficient semiconductor gas sensors for carbon dioxide detection

Abstract

In this paper investigated materials based on 0.9Ba1-xLaxTi1-yRyO3–0.1LaOCl (where R – Mn, Fe, Co, Ni, Cu) as sensing elements of power-efficient semiconductor CO2 gas sensors. During research found that the sensors on the basis of BLT with copper and nickel ions are characterized by the low values of energy consumption in comparison with other materials. Power consumption of equal fabricated sensors (70-90 mW) allows their use in energy-efficient autonomous alarm systems. In this paper were synthesized and investigated semiconductor nanomaterials based on doped barium-lanthanum titanate. The phase composition, structure and properties of the materials and operational characteristics of CO2 gas sensors on their base have been studied.
