Improved selectivity of SnO2:C alloy nanoparticles towards H2 and ethanol reducing gases; role of SnO2:C electronic interaction

Advanced development of metal oxide nanomaterials for H2gas sensing applications

“…When H 2 enters, the resistance changes dramatically, which enhances the performance of H 2 sensing. Bhatnagar et al279 studied the behavior of C-doped SnO 2 nanoparticles in gas sensing. They found that the material exhibited p-type sensing behavior for H 2 , n-type for ethanol, and achieved high selectivity detection for H .Other carbon nanomaterials with different morphologies, such as, carbon nanofibers92 and carbon nanotubes285 could pose a high sensitivity to low concentration H 2 after combined with MOx nanomaterials.…”

Fabrication of Electrochemical Sensor Based on CeO2−SnO2 Nanocomposite Loaded on Pd Support for Determination of Nitrite at Trace Levels

“…Also, SnO 2 is one of the most appropriate candidates in the design and diagnostic sensors because it has easy and low‐cost synthesis in addition to high stability . The oxide of these semiconductor metals (CeO 2 and SnO 2 ) have been studied due to their electrical and catalytic properties, the similarity of their energy levels, and their electrical conductivity . Fabrication of mixed nanocomposites based on gold and palladium metal nanoparticles have been studied in the past decades to improve their electrical conductivities and catalytic activities .…”

Co Katkılı SnO2 Numunelerinin Sentez ve Karakterizasyonu

“…SnO2 is a very stable material both chemically and thermally [5]. SnO2 has been used in the gas sensing applications (especially in the detection of the flammable, toxic and corrosive gases), lithium-ion batteries, anti-refractive coatings, transparent conducting electrodes, light-emitting diodes, solar cells, transistors, flat panel displays, catalysts, supercapacitors, memristors and so on due to its superior electrical, optical and electrochemical properties [6][7][8][9][10][11][12][13][14][15][16].…”
