Abstract
Iron oxyhydroxide (FeOOH) is an interesting material with major applications in water treatment. However, the gas-sensing properties of this nano-/micromaterial are not understood. Herein, we introduce a facile process for synthesizing submicron-sized γ-FeOOH spheres. The formation process of the γ-FeOOH phase after treatment is proposed, and the gas-sensing properties of the as-synthesized materials are investigated using NH3, H2S, NO2, and SO2. The influence of working temperature (from 25 °C to 300 °C) on material structure and gas-sensing performance is also studied and the gas-sensing process is explained and discussed. © 2019 Elsevier Ltd
