Abstract
Nanocomposites based on metal oxides (MOs) have attracted the attention of researchers worldwide due to their significant properties such as high active surface area, high porosity, and electrical conductivity. On the other hand, carbon nanotubes (CNTs) are important materials due to their high surface area, ease of functionalization, and high electrical communication. Nanocomposites-based MOs and CNTs (MOs-CNTs) act synergistically to increase electrochemical activity for the sensing of toxic chemicals. Electrochemical sensor-based MOs-CNTs composites are widely used for the determination of chemical processes, air�water impurities, and toxic ingredients in the environment. A number of MOs-CNTs nanocomposites have been reported for electrochemical sensing such as nickel oxide nanoparticles-decorated CNTs nanocomposites for 4-aminophenol chemical sensors, multiwalled CNTs NiO nanoparticles composites as enzyme-free electrochemical glucose sensors, phenolic sensor development based on chromium oxide-decorated CNTs for environmental safety, etc. Conclusively, MOs-CNTs are an excellent class of nanocomposites for the development of effective, reliable, cost-effective, and durable electrochemical sensors for toxic chemicals significant for environmental, biological, pathological, and pharmaceutical samples. � 2021 Elsevier Inc.
