“…Graphene-based polymer composites have been shown to display both higher mechanical properties and higher electrical properties when compared with other carbon-based polymer composites while at the same time not biasing them toward a subset of gases [ 42 , 48 ]. In one such study, Naikoo et al developed a sensing layer consisting of hybrid zeolite X/rGO in combination with PPy for the sensing of CO [ 48 ]. Zeolite insertion was responsible for both a decrease in PPy degradation and an increase in the sensitivity to CO, while the reduced graphene was the main factor in increasing the performance of the sensor [ 42 ].…”

Nanocomposite materials have seen increased adoption in a wide range of applications, with toxic gas detection, such as carbon monoxide (CO), being of particular interest for this review. Such sensors are usually characterized by the presence of CO absorption sites in their structures, with the Langmuir reaction model offering a good description of the reaction mechanism involved in capturing the gas. Among the reviewed sensors, those that combined polymers with carbonaceous materials showed improvements in their analytical parameters such as increased sensitivities, wider dynamic ranges, and faster response times. Moreover, it was observed that the CO reaction mechanism can differ when measured in mixtures with other gases as opposed to when it is detected in isolation, which leads to lower sensitivities to the target gas. To better understand such changes, we offer a complete description of carbon nanostructure-based chemosensors for the detection of CO from the sensing mechanism of each material to the water solution strategies for the composite nanomaterials and the choice of morphology for enhancing a layers’ conductivity. Then, a series of state-of-the-art resistive chemosensors that make use of nanocomposite materials is analyzed, with performance being assessed based on their detection range and sensitivity.

“…Figure (f) displayed the XRD pattern of PPy@MnO 2 ‐CC electrodes. The diffraction peak located at 25.8° was indexed to the characteristic of amorphous PPy . The intensities of MnO 2 diffraction peaks became weaker, further indicating that the surface of MnO 2 nanoflowers was covered by PPy.…”

BACKGROUND: The morphology and size of MnO 2 that deposited on a carbon clothelectrode have dramatic effects on the electrochemical properties and cycling life. Currently, MnO 2 and its composite structures with zero-dimensional (0D) nanospheres, one-dimension (1D) nanotubes and two-dimension (2D) nanomesh have been successfully synthesized and employed in MFC. Hence, the development of a three-dimensional (3D) flexible, cost-effective and high-performance anode is of great significance for microbial energy harvesting.RESULT: Herein, we have fabricated 3D cauliflower-like polypyrrole@manganese dioxide (PPy@MnO 2 ) composites, which are successfully grown on carbon cloth (CC) anode by electrodeposition to promote the power production and storage in microbial fuel cells (MFCs). Impressively, the as-prepared PPy@MnO 2 modified CC anode delivers a power density of 2139.7 ± 17.5 mW m −2 and produces an areal capacitance of 1120 ± 12.8 mF cm −2 , which is 3.58 and 4.84 folds higher than that with bare CC anode, benefiting from the unique cauliflower-like 3D architecture with increased active centers that host the bacteria for more efficient charge transfer. Electrochemical analyses indicate that the PPy@MnO 2 modified CC electrode has excellent electrochemical activity, capacitive behavior and long-term cyclabilities with smooth surface morphology and high porosity.CONCLUSION: These findings not only provide a facile electrodeposition strategy for PPy@MnO 2 nanoflowers modified CC anode, but also demonstrates its potential for the production and storage of energy simultaneously in MFC application. RESULTS AND DISCUSSION Anode modificationThe surface morphologies of the MnO 2 -CC electrodes with different MnO 2 deposition times from 30 min to 120 min are presented in Fig. 2(a-d).

“…PPy is one of the most widely used conducting polymers in different applications due to its high conductivity, facile synthesis process, and great environmental stability [ 132 ]. Graphene and PPy nanocomposites had also become appealing sensor materials due to their combined effects, and better electrochemical performance compared with pure PPy and graphene [ 133 ]. Rawoof A. Naikoo and Radha Tomar [ 134 ] investigated a CO gas sensor using Zeolite-X/reduced graphene oxide/polypyrrole (Na-X/rGO/PPy) nanocomposite as a sensing material.…”

The use of graphene and its derivatives with excellent characteristics such as good electrical and mechanical properties and large specific surface area has gained the attention of researchers. Recently, novel nanocomposite materials based on graphene and conducting polymers including polyaniline (PANi), polypyrrole (PPy), poly (3,4 ethyldioxythiophene) (PEDOT), polythiophene (PTh), and their derivatives have been widely used as active materials in gas sensing due to their unique electrical conductivity, redox property, and good operation at room temperature. Mixing these two materials exhibited better sensing performance compared to pure graphene and conductive polymers. This may be attributed to the large specific surface area of the nanocomposites, and also the synergistic effect between graphene and conducting polymers. A variety of graphene and conducting polymer nanocomposite preparation methods such as in situ polymerization, electropolymerization, solution mixing, self-assembly approach, etc. have been reported and utilization of these nanocomposites as sensing materials has been proven effective in improving the performance of gas sensors. Review of the recent research efforts and developments in the fabrication and application of graphene and conducting polymer nanocomposites for gas sensing is the aim of this review paper.
