“…Phosphorous doping also can be used alongside N-doping to improve uranyl ion adsorption, specific capacitance (95.4 F g -1 ), and charge transfer, resulting in improved adsorption rate and binding capacity (300.6 mg/g) [48]. Extrinsic binding sites can be appended through the addition of phosphates [47], phytic acid (containing phosphate groups) [41,42,61], chitosan (polysaccharide containing hydroxyl, amino, and acetamido groups) [62][63][64][65], and xanthan gum (polysaccharide containing hydroxyl and carboxylic acid groups) [65]. For example, by incorporating phytic acid into a polypyrrole-carbon felt electrode, Huang et al were able to increase the equilibrium adsorption of uranyl nitrate from 372.8 to 1562.0 mg/g under alternating voltage conditions (Figure 3) [41].…”

Electrochemical removal of uranium from water is an emerging topic that addresses the treatment of drinking water, remediation of contaminated sites, and mining from seawater. Electrochemical strategies compare favorably to conventional processes, such as adsorption and coagulation/flocculation, with advantages in speed and efficiency, materials regeneration, uranium recovery, and recycling. This review assesses all published work on electrochemical techniques for uranium extraction from water, including capacitive deionization (electrosorption), electrodeposition, electrodialysis, and electrocoagulation. This work compares these approaches with conventional techniques and discusses their applicability in different use cases. Environmental and economic considerations are discussed, as well as the current outlook and opportunities for engagement in this emerging field.

“…Though the electrochemical uranium extraction method has been well established, the developed electrode materials still have some drawbacks. Conventional functional electrode materials possess a low specific surface area, leading to limited available active sites . M–N x –C–R electrocatalysts need to mix with binders and conductive agents to prepare the electrodes. , This process is complicated, and the active materials easily fall off after multiple processing steps.…”

Uranium extraction from seawater (UES) is crucial for ensuring the sustainable development of nuclear power and has seen significant advancements in recent years. However, natural seawater is a highly complex biogeochemical system, characterized by an extremely low uranium (U) concentration (≈3.3 µg L−1), abundant competitive ions, and significant marine biological pollution, making UES a formidable challenge. This review addresses the challenges encountered in UES and explores potential methods for enhancing the industrial UES system, including membrane separation, electrochemistry, photocatalysis, and biosorption. Additionally, several representative marine tests are summarized and restrictive factors of large‐scale UES are analyzed. Finally, the further development of UES from laboratory to industry applications is promoted, with a focus on technological innovation. The goal is to stimulate innovative ideas and provide fresh insights for the future development of the UES system, bridging the gap between laboratory research and industrial implementation.
