The development of SnO2-based recoverable gas sensors for the detection of DMMP

Origin and role of elasticity in the enhanced DMMP detection by ZnO/SAW sensor

“…Although sensor was insensitive to few interferants yet methanol was giving significant response. It is to be noted that metal oxides were not exploited much as chemical interface layer on SAW devices despite the fact that they are stable and exhibits good sensitivity toward DMMP vapors using conductometric technique [13]. The composites of SnO 2 with various other oxides (NiO, Y 2 O 3 , Nb 2 O 5 , CuO, Yb 2 O 3 , BaO and La 2 O 3 ) were also used as sensing element [13].…”

Effects of Additives on the DMMP Sensing Behavior of SnO2Nanoparticles Synthesized by Hydrothermal Method

“…5 shows the DMMP response behaviors of the undoped SnO 2 nanoparticles and Ni-, Sb-, Nb-doped SnO 2 nanoparticles. The ratio of additives was fixed to 5 wt% based on the previous report in all samples [20]. The addition of additives decreased the magnitude of the gas response, but the recovery behavior was significantly improved.…”

“…However, semiconductor metal oxide sensors for DMMP exhibit a poisoning effect due to the irreversible reaction between surface atoms of the metal oxides and phosphorus atom of the DMMP molecules [18,19]. To solve this problem, various metal oxides have been added to the SnO 2 particles [20,21].…”

Synthesis and characterization of porous WO 3 –SnO 2 nanomaterials: An infrared study of adsorbed pyridine and dimethyl methylphosphonate

“…Recent studies reported the development of various nano-sized metal oxides [29][30][31][32], mixed oxides systems [33,34], and porous A c c e p t e d M a n u s c r i p t 3 and the operational temperature problems have been vastly improved using various solid blending SMO materials [37,38]. WO 3 is one of the SMO based sensors that are known to provide sensitive detection for sarin, one of the most popular chemical warfare agents (CWA).…”
