Recent advances in anodic anaerobic ammonia oxidation in microbial electrolysis cells
Electricity-driven anaerobic ammonia oxidation (anammox) has garnered extensive attention as a novel, up-and-coming ammonium removal technology because of its broad, cost-efficient, and eco-friendly application. However, the anammox occurring in anode did not receive the attention it deserved. The underlying mechanisms, regulatory strategies, and technical and economic potential of anodic anammox technology are still poorly understood. Thus, we discussed the recent advance in anodic anammox, emphasizing the associated bacteria groups, and assessed the technological and economic potential of the process in terms of operating conditions and energy consumption. It was unravelled that the energy consumption of anodic anammox varies from 0.002 to 0.80 ± 0.09 kWh kg−1 N. This review can improve our understanding of anodic anammox and provide a theoretical foundation for future regulation and practical applications.
期刊介绍：
The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner:
1.The views of experts on current advances in electrochemistry in a clear and readable form.
2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle:
• Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
