Nanosized particles of α- Fe 2 O 3 in the range of 17–64 nm were synthesized via hydroxide precipitation. The synthesized powder was investigated by XRD employing CuK α radiation and 2θ geometry. SEM images show the nanosheet like morphology. The pellet of this sensing material was made by hydraulic press under a uniaxial pressure of 616 MPa. The LPG sensing properties of α- Fe 2 O 3 were investigated at room temperature for different exposure times of LPG. A maximum value of sensitivity and sensor response were found 3 and 213%, respectively for an exposure time of 300 s. Electrical properties of α- Fe 2 O 3 in air were also investigated by measuring temperature–resistance (R–T) characteristics and plotting them as Arrhenius plot. Activation energy was calculated by thermal resistance method and found to have a value 1.07 eV.

In this paper, carbon nanotubes (CNTs) were functionalized by acid treatment and further functionalized with dodecylamine and were designated as CNT-carboxylic and CNT-amide, respectively. Then, functionalized CNTs produced were characterized with various methods to verify the attachment of a functional group. Performance of the functionalized CNTs in the detection of benzene gas was monitored at room temperature. The sample was dropped cast on the interdigitated transducer (IDT), and the changes in resistivity were recorded by a digital multimeter in a customized chamber under controlled humidity (∼55%) environment. Based on the findings, it showed that the functionalized CNTs provide an extra active area for interaction between the gas analyte and CNTs, thus increasing their response and improving the sensitivity of the sensing material.
