Abstract
Fe3O4/FeOOH nanocomposites were synthesized by a simplistic precipitation method for high-performance gas sensing applications. A spray-coating method was used to deposit a sensitive film of Fe3O4/FeOOH nanocomposites on a quartz crystal microbalance (QCM). The structural and morphological characteristics were analyzed by using X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectrometry (EDS), Fourier transforms infrared (FTIR) spectroscopy, and a vibrating sample magnetometer (VSM). The average diameter and length of the FeOOH nanorods were 30 and 100 nm, respectively. The maximum saturation magnetization of the prepared Fe3O4/FeOOH nanocomposites obtained a value ~30 emu g−1. The QCM sensor based on the Fe3O4/FeOOH nanocomposites was measured with various concentrations of toxic gases (CO, NO2, SO2) at room temperature. The gas sensing results indicated that the developed sensor had a considerable potentiality to apply for toxic gas sensors with a high detection sensitivity, repeatability, and good stability.
