In situ decoration of Zn2SnO4 nanoparticles on …

Developing novel metal oxide semiconductor (MOS) gas-sensing materials with high performance has attracted much attention in the field of gas sensor. In this work, Zn2SnO4 nanoparticles/reduced graphene oxide (ZTO/RGO) nanocomposites with various contents of RGO were successfully synthesized via a solvothermal method combined with subsequent annealing process. Through the …

In situ decoration of Zn2SnO4 nanoparticles on reduced graphene oxide ...

15/04/2018· In general, when the ZTO sensor is exposed to air ambient, oxygen molecules will absorb on the surface of ZTO NPs. Owing to the strong electronegativity of oxygen atom, the absorbed oxygen molecules can capture electrons from the conduction band of ZTO, and then produce chemisorbed oxygen anions (O 2-, O-or O 2-). In this case, a thick EDL will form on the surface of ZTO NPs, …

Characterization and gas sensing properties of PPy–Zn 2 SnO 4 ...

30/05/2019· Their results showed that the PPy–ZTO sensor exhibited enhanced sensing properties toward NH 3 gas compare to the pure PPy and ZTO counterparts. However, it is still a challenge to prepare PPy–ZTO nanocomposite as a sensing materials by a simple and cost-effective route. In addition, it found that various parameters such as crystallite size, porosity, morphology, nature and …

than that of the bare ZTO sensor. Besides of high sensitivity, the 8ZTO/RGO sensor also showed impressive selectivity and fast response/recover behavior, as well as good linearity in a relatively wide range of ethanol concentration (5–1200 ppm). These good sensing characteristics make 8ZTO/RGO a promising candidate for practically detecting ethanol. The gas-sensing mechanism of the composite to …

A comparative study on the VOCs gas sensing properties of …

The developed ZTO sensor maintained its performance after several tens of testing cycles, and few months storage in ambient air. The high gas-sensing performance of the ZTO hollow cubes and hollow octahedra to acetone was explained by an increase in the pore size, porosity, and oxygen vacancies. The above results suggest that the ZTO hollow octahedra and the hollow cubes are promising sensing …
