Temperature Dependence of Sensors Based on Silver-Decorated Nitrogen-Doped Multiwalled Carbon Nanotubes

<div>Ag-NPs anchored on the surface of CN<sub><i>X</i></sub>-MWNTs-Ag. (a) Scanning electron microscopy (SEM) image. ((b) and (c)) Transmission electron microscopy (TEM) images. (d) X-ray diffraction pattern of decorated and nondecorated CN<sub><i>X</i></sub>-MWNTs. The C(002) peak is characteristic of MWCNTs; peaks at ~43 degrees correspond to encapsulated FeC<sub>3</sub>, normally observed in MWCNTs. (e) Scanning electron microscopy (SEM) image of the sensor device which consists of a foil formed by CN<sub><i>X</i></sub>-MWNTs-Ag. (f) Sensor device photograph showing the nanotube foil over the copper electrodes.</div>
