Formic Acid Gas Sensors Based on Electrolytically Exfoliated Graphene-loaded Flame-Made Spinel Zn2SnO4 Composites
In this w ork, effective gas-sensing material were prepared by combining spinel zinc stannate (Zn2SnO4) nanoparticles synthesized by flame spray pyrolysis and graphene produced by the electrolytic exfoliation for volatile organic acids (VOAs) detection. The effect of graphene content in the range of 0.2–5 wt% on formic acid (HCOOH)-sensing performance of Zn2SnO4 nanoparticles was evaluated. Structural, physical, and chemical properties were investigated using X-ray diffraction, Raman spectroscopy, BET-surface analysis, energy dispersive X-ray spectroscopy, and electron microscopy. From the gas-sensing test towards 0.005-0.1 vol% HCOOH in dry air at 200-400°C, the graphene-loaded Zn2SnO4 sensor with the optimal graphene content of 0.5 wt% displayed the highest response of ~4970 towards HCOOH at the optimal temperature of 300°C. Moreover, it showed high HCOOH selectivity against several other VOAs, volatile organic compounds, and environmental gases. Therefore, graphene-loaded spinel Zn2SnO4 sensors could be attractive choices for selective HCOOH detection and useful for food science and industrial applications.
期刊介绍：
The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
