An antimonate composite material based on a heterostructure junction and preparation and application thereof
By constructing heterogeneous isomorphic antimonate composite materials, the problems of low response and weak selectivity of TiO2 materials in gas-sensitive applications were solved, achieving high response, low detection limit and excellent selectivity for n-propanol, which is suitable for environmental monitoring and breath diagnosis.

Abstract
This invention belongs to the field of gas sensor technology, specifically relating to an antimonate composite material based on heterogeneous isomorphism, its preparation, and its application. It utilizes bimetallic antimonate Ni... x Mg 1‑x Sb₂O₆ or antimonate / titanium dioxide composite Ni x Mg 1‑x A n-propanol gas sensor was fabricated using Sb₂O₆ / TiO₂ as the sensitive material. At the optimal operating temperature, it achieved a response value of over 35 for 20 ppm n-propanol, with a detection limit as low as 20 ppb and excellent selectivity. It shows great potential in environmental monitoring, industrial production, and early disease screening through breath analysis.
