Abstract
A room temperature nitrogen dioxide gas sensor comprising tin(IV) oxide decorated with gold nanoparticles is described. The tin(IV) oxide may have an average layer thickness of 10-1,000 nm, and is topped with dispersed gold nanoparticles having an average longest dimension of 200-650 nm. The room temperature nitrogen dioxide gas sensor may be used to detect and measure levels of nitrogen dioxide gas at room temperature and at concentrations of 100 ppb-1800 ppm, with a high stability. A method of making the room temperature nitrogen dioxide sensor is also described, and involves sputtering to deposit a tin(IV) oxide layer and a gold layer on a substrate, followed by annealing.
