The chemical cataluminescence sensor did not require an external light source and a complicated circuit, which avoids scattering of light, it has high sensitivity and selectivity, and has a wide linear range, so researchers have shown a great interest in this type of sensor. However, when the chemical cataluminescence sensor was used for routine analysis, it was found that there are still some deficiencies, mainly the short sensor life and signal drift caused by the consumption of luminescent reactants, thus limiting the cataluminescence sensor in practice. The application of the analysis is particularly important to develop a cataluminescence sensor with high sensitivity and stability, simple production, and long life and practical application. The continuous development of nanotechnology has provided new opportunities for the research of cataluminescence sensors. Certain gases can generate strong chemiluminescence on the surface of certain nanomaterials. Therefore, nanomaterials can be used to design different types of catalytic luminescence sensors for sensitive materials. In this paper, nano-catalysts were used as sensitive materials, and a catalyzed luminescence sensor array is designed to broaden the application range of catalytic luminescence.
