Fabrication of an efficient hierarchical mesoporous 2D-MoS2/CNT/polypyrrole based composite electrodes for competitive and selective U6+ removal using capacitive deionization: Mechanistic evaluation through cyclic voltammetry

Developments in conducting polymer-, metal oxide-, and carbon nanotube-based composite electrode materials for supercapacitors: a review

“…The electrodes in PCs are made of highly conductive materials, such as Activated Carbon (AC), graphene, CNT, CP, and MO-based composites, which provide a large surface area for electrochemical reactions. [34][35][36][37] The quick charge transfer reactions due to the adsorbed species on the electrode surface depend upon UPD, intermediates adsorbed on ions present in the electrolyte, and electrode composition. 28 The electrolyte is a liquid or gel-like substance containing ions that facilitate the charge transfer between the electrodes.…”

“…In HCs, the hybrid system delivers a combination of both blending a power source that is an electrode that functions like a capacitor and a source of energy that is an electrode that functions like a battery in the same cell. 35,36 HCs, also known as asymmetric capacitors, are a type of ESD that combines the features of both capacitors and rechargeable batteries. They are designed to provide a balance between high power density (like capacitors) and high EDs like LIBs, making them suitable for applications that require both rapid charge/discharge capabilities and long-term energy storage.…”

Electrochemical Techniques for Uranium Extraction from Water

“…Subsequently, much of the electrode's surface area can become inaccessible. As such, it is more advantageous to use a hierarchical pore structure with sufficient macro-and mesoporous structure to improve the diffusion of the electrolytes throughout the electrode [43][44][45][46]. Liu et al, for example, showed that nitrogen-doped hierarchical porous carbon had improved uranyl electrosorption capacity (67.25 mg/g) by 26-29% relative to similar electrodes without hierarchical structures [43].…”
