The synergistic effect of fluorination and embedded SnO2 on the NO gas sensing of expanded graphite

Oxygen vacancy engineered tin dioxide/tungsten disulfide heterostructure construction for effective NO sensing

“…To sum up, benefiting from the heterojunction between SnO 2 and WS 2 , the SnO 2 /WS 2 hybrid not only acquires the superior response but also achieves a fast response and recovery time. The response and response/recovery time of the related MOS sensing materials are summarized in Table 1, 13,39,41–44 further confirming the strong response at a low operating temperature with an extremely high response/recovery speed.…”
