Abstract
The development of butyl acetate sensors with high sensitivity and selectivity has been highly desirable for its harmful effects on human health. In this work, we developed a high-performance butyl acetate sensor based on vascular bundle structure Zn2 SnO4 nanomaterial derived from maize straw. The vascular bundle structure Zn2 SnO4 with higher specific surface area obtained by calcination to remove the maize straw template, plays the dual role of accelerating the diffusion of gas molecules and providing more active sites. Our research showed that the sensor had a response of 18 to 100 ppm butyl acetate at a working temperature of 250 °C, with a fast response recovery rate (18 s/25 s), which showed significant improvement compared to the Zn2 SnO4 sensor prepared without templates. The improved performance can be attributed to the cross-linked nanoparticle chains and gas collision mechanism of the sensor. These findings highlight the potential of our sensor for the detection of butyl acetate gas.
