Organically hybridized SnO2 gas sensors

Synthesis of tin oxide nanosized crystals embedded in silica matrix through sol–gel process using alkoxide precursors

“…It has been reported that the FTIR absorption band of SnAOASi are located at 620 and 940 cm À1 [34][35][36] where the former is not observed in all the cases. It is difficult to distinguish the bands of SiAOH ($960 cm À1 ), SnAOH ($945 cm À1 ) and SnAOASi ($940 cm À1 ).…”

Fine nanoparticles of Al–SnO2 prepared by a co-precipitation route in water/oil microemulsion

“…Nanosized SnO 2 has been extensively studied because of its wide applications such as gas sensors [1][2][3][4], electrode materials [5,6], catalyst supports [7], solar cells [8,9], etc. In order to improve the properties of SnO 2 nanoparticles, doping is the most important means [10][11][12][13][14][15][16][17][18][19][20][21].…”

Modified SnO2-APTES gas sensor for selective ammonia detection at room temperature

“…1. The peak at 938 cm -1 is attributed to Sn-O-Si stretch [6]. The strong absorption peaks at 1029 and 1125 cm -1 are attributed to Si-O bond of polymerized APTES on the surface.…”
