Improved formaldehyde sensor of Zn2SnO4/SnO2 microcubes by compositional evolution and Y2O3 decoration
Source abstract
Abstract
Abstract Zn2SnO4/SnO2(ZTO/SnO2) and Y doped Zn2SnO4/SnO2(ZTO/SnO2) microcubes were synthesized by a hydrothermal route at 130 °C and subsequently used for obtaining gas sensors. To evaluate the structure, morphology, chemical state and optical bandgap, our sensors were characterized by XRD, SEM, XPS and UV–vis analysis. Compared with sensors based on ZTO/SnO2 microcubes, the Y doped ZTO/SnO2 microcubes had an optimum sensing performance to 100 ppm formaldehyde (HCHO), for instance lower working temperature (210 °C) and better response (46.07). In addition, the enhanced sensing mechanism of Y doped ZTO/SnO2 microcubes was discussed in detail.
