SnS2 microflowers loaded with Pt nanoparticles with electron sensitization enhanced n-butanol gas sensitivity at low operating temperature

We have fabricated the Pt doped SnS2 microflowers successfully, and the Pt doped SnS2 sensor shows superior gas-sensing performance toward n-butanol. [Display omitted] •The Pt-doped SnS2 microflowers with voids and pores was prepared by hydrothermal method.•The Pt/SnS2 sensor shows excellent gas sensing performance to n-butanol.•The LOD of 3 % Pt/SnS2 sensor to n-butanol was 14.76 ppb. N-butanol is flammable and can explode in open air. The Pt-doped SnS2 microflowers with voids and pores was prepared by hydrothermal method to detect N-butanol. We used XRD, SEM, XPS and UV–vis to characterize the samples. Finally, the response value, response/recovery time, stability et.al and enhanced sensing mechanism to n-butanol were investigated too.
