Simple solid-state chemical synthesis and gas-sensing properties of spinel ferrite materials with different morphologies
Source abstract
Abstract
Abstract Spinel ferrite materials with different morphologies were synthesized by simple solid-state chemical reactions under mild reaction conditions and their gas-sensing properties were investigated in detail. It was found that all sensors based on the as-prepared materials had high responses, low working temperatures, rapid response/recovery characteristics, good selectivity and long-term stability to methanal and ethanol. Among them, ZnFe 2 O 4 exhibited the best response, which was attributed to its intrinsic semiconductor nature and suitable microstructure. The response value reached 37.3 for 100 ppm of methanal at 260 °C and 29.1 for 100 ppm of ethanol at 300 °C. The response and recovery times were not longer than 5 s and 26 s. This study has yielded helpful insights to explore gas-sensing materials with good comprehensive performance.
