Nitric oxide detection element and process for producing same

摘要

Provided are a nitric oxide detection element capable of detecting NO gas contained in a mixed gas at a high speed even when the amount thereof is a super trace amount of ten and several parts per billion; and a process for producing the element. In a nitric oxide detection element having a substrate 12 and a sensing film 11 formed on a surface of the substrate, the sensing film is composed of nitric oxide sensing particles and a polymer adhesive. The nitric oxide sensing particles are produced by adsorbing a dye having a porphyrin skeleton and having, as a central metal, divalent cobalt onto surfaces of inorganic particles.
