In view of the importance of rapid detection of H2O2, a carbon-based three-dimensional conductive network consisting of multiwalled carbon nanotubes (MWCNTs) and reduced graphene oxide (rGO) was introduced into the preparation of SnS2 to obtain SnS2/MWCNTs/rGO modified composite, which was prepared by one-step hydrothermal method. When the mass ratio of MWCNTs and rGO was 1:1, the composite had the best detection effect on H2O2. At this time, SnS2 was uniformly distributed on the surface of tubular MWCNTs and flaky rGO, and MWCNTs were interspersed between layers of rGO. The synergistic effect of the three materials showed a high current response ability for the detection of H2O2. During the range of 0.238 ~ 12.267 mmol·L− 1, the linear equation was Ipc(mA) = -0.029–0.019c(m mol·L− 1), with a sensitivity of 388.28 µA·mmol− 1·L·cm− 2 and a detection limit of 0.236 µmol·L− 1(S/N = 3). Moreover, the prepared modified electrode also had a good selectivity, reproducibility and stability.

“…Additionally, this modified electrode achieved recoveries ranging between 97.1% to 102.9% for real samples of commercial fruit juices of papaya, tomato, and orange. A layer-by-layer modification of GCE was presented by Fang Y. et al [ 154 ]. After potentiostatic deposition of nickel on glassy carbon electrode, CNTs were grown by catalytic chemical vapor deposition (CCVD) followed by PANI potentiodynamic polymerization from aqueous aniline solution.…”

Electrochemical sensors appear as low-cost, rapid, easy to use, and in situ devices for determination of diverse analytes in a liquid solution. In that context, conducting polymers are much-explored sensor building materials because of their semiconductivity, structural versatility, multiple synthetic pathways, and stability in environmental conditions. In this state-of-the-art review, synthetic processes, morphological characterization, and nanostructure formation are analyzed for relevant literature about electrochemical sensors based on conducting polymers for the determination of molecules that (i) have a fundamental role in the human body function regulation, and (ii) are considered as water emergent pollutants. Special focus is put on the different types of micro- and nanostructures generated for the polymer itself or the combination with different materials in a composite, and how the rough morphology of the conducting polymers based electrochemical sensors affect their limit of detection. Polypyrroles, polyanilines, and polythiophenes appear as the most recurrent conducting polymers for the construction of electrochemical sensors. These conducting polymers are usually built starting from bifunctional precursor monomers resulting in linear and branched polymer structures; however, opportunities for sensitivity enhancement in electrochemical sensors have been recently reported by using conjugated microporous polymers synthesized from multifunctional monomers.

Polymer nanocomposites exhibit idiosyncratic physicochemical features that cannot be achieved by the respective individual constituting materials. Owing to their unique properties, they have witnessed widespread application in numerous areas of electrochemistry such as supercapacitors, batteries, solar cells, energy storage, and electrochemical sensors. By combining polymeric materials such as polyaniline (PANI), polyacetylene (PAc), polypyrrole (PPy), polythiophene (PTn), or poly(3,4-ethylenedioxythiophene) (PEDOT) with different fillers, for example, carbon nanotubes (CNTs), graphene (Gpn), metal nanoparticles (MNPs), and metal−organic frameworks (MOFs), several composites materials have been fabricated. Electrochemical sensors are very selective, sensitive, and low-cost materials for the effective detection of target molecules. This review summarizes some conventional conducting polymer-based nanocomposites and their utility as electrochemical sensors. Lastly, a discussion on the future perspectives of conducting polymer nanocomposites is also included.
