It is reported that the response is dependent on its specific surface area, and the response/recovery rates are on the electron transfer channels. In this work, the authors have designed a type of fluffy hematite (alpha-Fe2O3) microtubes. Results indicate that these fluffy alpha-Fe2O3 microtubes are highly porous and composed of interconnected ultrafine nanorods. And the assembled gas sensors show a response of 16.8 to 100-ppm ethanol gas at 260 degrees C, the response time is of 2 s and the recovery time is of 25 s. Moreover, the sensors also show good gas selectivity and long-term stability. (C) 2018 Elsevier B.V. All rights reserved.
