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.

: Formaldehyde is a ubiquitous and high toxicity gas. It is an essential task to efficient detect owing to their toxicity and diffusion. In this work, we studied on the detection of trace amount of formaldehyde based on hollow Co<sub>3</sub>O<sub>4</sub> nanostructure. It is found that Co<sub>3</sub>O<sub>4</sub> hollow spheres with different structures shows distinct sensing performance towards formaldehyde at room temperature, the response value of nanosheet modified Co<sub>3</sub>O<sub>4</sub> towards 100 ppm formaldehyde will reach 35 in 18 second, and the nanoparticle modified Co<sub>3</sub>O<sub>4</sub> hollow sphere will reach 2.1 in 18 second, 17 in 300 second. The nanosheet modified and nanoparticle modified Co<sub>3</sub>O<sub>4</sub> hollow sphere will reach 4 and 20 in 10 second towards 100 ppm formaldehyde at room temperature. As room temperature, the sensors do not response towards NH<sub>3</sub>, CO, etc. The sensing mechanism was proposed based on the theoretical and experimental results. The Co<sub>3</sub>O<sub>4</sub> sensor shows that potential utility in CH<sub>2</sub>O quick sensing at room temperature
