A Review on Recent Developments in Carbon Nanotube‐Based Composite Materials for Electrochemical Sensors and Supercapacitor Applications

Abstract Carbon Nanotubes (CNTs) are carbon‒based materials with superior physicochemical qualities that are both inexpensive and sustainable. CNT has previously been widely employed as an effective electrode material for energy storage applications and the development of electrochemical sensors. The occurrence of synergistic interactions taking place between composites of CNT with metal oxides, metal sulfides, and carbon/polymer are responsible for enhanced electrochemical characteristics. Consequently, a variety of composite materials based on CNTs have been developed and produced for utilization in energy storage and electrochemical sensing. This brief review article provided an overview of the advancements made in electrode materials, including CNTs and their composites for fabrication of energy storage devices and electrochemical sensors. We anticipate that the researchers working on the development of CNT‒based electrode materials for electrochemical sensing and energy storage applications would find this review article useful.
