Enhanced trimethylamine gas-sensing performance of CeO2 nanoparticles-decorated MoO3 nanorods
The MoO 3 nanorods decorated with CeO 2 were successfully synthesized by a two-step hydrothermal method, and the microstructure and morphology of CeO 2 /MoO 3 were determined by XRD, XPS, SEM, and TEM. It can be confirmed by SEM that the CeO 2 nanoparticles of uniform size were successfully compound...

were successfully synthesized by a two-step hydrothermal method, and the microstructure and morphology of CeO

/MoO

were determined by XRD, XPS, SEM, and TEM. It can be confirmed by SEM that the CeO
2
nanoparticles of uniform size were successfully compounded with MoO
3
nanorods. According to the gas sensitivity test results, the response value of the CeO
2
/MoO
3
sensors to trimethylamine gas has been enhanced by about 20 times, and the excellent catalytic performance of CeO
2
and the conversion of the oxidation state of Ce ions have played a vital role. The analysis of XPS spectrum reveals the effect of the conversion of Ce
3+
ions and Ce
4+
ions on the enhancement of gas sensitivity. In addition, the gas-sensing mechanism of CeO

/MoO

is discussed based on the change of resistance value, which shows the great potential of CeO

in the field of gas sensing. |
