Performance of 3D SnO2 microstructure with porous nanosheets for acetic acid sensing
چکیده انگلیسی
The porous flower-like SnO2 was successfully synthesized by a simple hydrothermal strategy and followed by calcination. The well-defined nanoflower was composed of thin nanosheets, which has many pores on its surface. The sensor based on these porous SnO2 nanoflowers showed excellent selectivity, fast response-recovery capability and high response to acetic acid at 340 °C. The response and recovery time were about 11 s and 6 s, respectively. The enhancement in gas sensing properties was attributed to their unique structures, including the 3D hierarchical structure and porous feature. The present study could be applied to the acetic acid detection.
