Highly selective environmental sensors based on flame-spray-made SnO2 nanoparticles

NO sensing by single crystalline WO3 nanowires

“…Phanichphant et al prepared ZnO [7] films and SnO 2 [8] nanoparticles by flame spray technique and got a good response to NO 2 . Owing to its high response, WO 3 , an ntype semiconductor with a bandgap of 2.8 eV, is one of the most promising materials for the sensing of NO x gases.…”

Low temperature acetylene gas sensor based on Ag nanoparticles-loaded ZnO-reduced graphene oxide hybrid

“…Tamaekong et al [2] reported a Pt/ZnO thick film-based C 2 H 2 sensor at a working temperature of 300 • C with a sensor response of 43 (for 1000 ppm). Zhang et al [3] hydrothermally synthesized a hierarchical nanoparticle (NP)-decorated ZnO microdisk-based C 2 H 2 sensor with a large detection range (1-4000 ppm) and very high response (7.9 for 1 ppm) at 420 • C. Dong et al [4] reported arc plasma-assisted Ag/ZnO composites for C 2 H 2 sensing, which had a maximum response of 42-5000 ppm C 2 H 2 at 120 • C. In addition, SnO 2 NPs [5], Pd-SnO 2 [6], Sm 2 O 3 -SnO 2 [7], Au/MWCNT [8], Ag/Pd-SiO 2 [9], etc, have been studied for C 2 H 2 sensing. However, high working temperature, low sensitivity and synthesis-process complexity, are still a great challenge.…”

Thermokinetic characterisation of tin(II) chloride

“…These properties are attractive for many applications such as highly selective environmental sensors [10], ultraviolet photodetectors [7] and electrode materials for Li-ion batteries [8].…”

“…Zero-dimensional SnO 2 nanoparticles have been synthesized by various synthesis methods such as sol-gel process using SnCl 2 Á2H 2 O [11,12], decomposition of [Sn(NMe 2 ) 2 ] 2 [13], SnSO 4 [8] or SnC 2 O 4 [14], hydrothermal synthesis using SnCl 4 Á5H 2 O [15] and flame spray pyrolysis of [CH 3 (CH 2 ) 3 CH(C 2 H 5 )CO 2 ] 2 Sn [10]. However, these techniques are either complex or require expensive starting materials.…”
