Morphology and size effect of Pd nanocrystals on formaldehyde and hydrogen sensing performance of SnO2 based gas sensor

Gaojie Li et al.

Summary: The morphology and size effect of Pd nanocrystals on the gas sensing performance of SnO2 were investigated. The Pd-SnO2 composites with different sizes and morphologies showed selectivity to H-2 and HCHO. The size effect was found to be more significant than the morphology effect, and the 2%PdNP-SnO2 composite exhibited the best sensing performance among all the composites with different sizes. The Pd-NC1-SnO2 and Pd-OC-SnO2 composites showed better sensing performance to HCHO and H-2, respectively, among the composites with similar sizes but different shapes.

Low temperature operated highly sensitive, selective and stable NO2 gas sensors using N-doped SnO2-rGO nanohybrids

Mrudul Modak et al.

Summary: In this study, SnO2-rGO and N-doped SnO2-rGO nanohybrids were synthesized by a facile hydrothermal method. The synthesized nanohybrids exhibited a tetragonal rutile structure of SnO2 lattice. Various characterization techniques were used to investigate the structural, chemical, morphological and optical properties of the nanohybrids. The gas sensing properties of the nanohybrids were also studied in detail, showing excellent NO2 sensing response at low temperature and low gas concentration, as well as remarkable stability. The superior performance can be attributed to the synergetic effect of small particle size, high defect concentration and high surface area.
