Abstract Zn₂SnO₄ was synthesized through a solid-state reaction between ZnO and SnO₂ under thermal treatment, forming a bimetallic oxide solid solution with exceptional gas sensing performance. In this study, Zn₂SnO₄ was initially synthesized via a hydrothermal method and subsequently combined with graphene aerogel. To circumvent phase degradation during secondary hydrothermal processing, pyrrole monomer polymerization under thermal activation was leveraged to promote the self-assembly of graphene oxide. The composite material was then obtained through displacement processing and freeze-drying, yielding Zn₂SnO₄/graphene aerogel. This material exhibits superior adsorption properties, demonstrating a response value of 4.0 at 130 ℃ for 10^-5 n-butanol vapor, with a theoretical detection limit as low as 4.7×10^-9, meeting stringent requirements for high-precision gas sensing. Notably, n-butanol is a component of exhaled breath in lung cancer patients. The development of Zn₂SnO₄/graphene aerogel-based gas-sensitive materials holds potential for preliminary screening and diagnosis of early-stage lung cancer, thereby expanding the medical applications of gas sensors.
