Abstract

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 (α-Fe₂O₃) microtubes. Results indicate that these fluffy α-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 °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.
