Efficient Electrochemical Nitrate Reduction to Optimize the Nitrogen Cycle
Abstract
This study investigates the potential of electrochemical nitrate reduction (ECNR) technology in optimizing the nitrogen cycle, addressing the critical issue of nitrate pollution. By examining various electrode materials, operational parameters, and system designs, the research aims to enhance the efficiency and selectivity of nitrate reduction. Experimental results reveal significant variations in nitrate reduction efficiency among different electrode materials, with platinum demonstrating the highest performance. The study underscores the importance of material selection, electrolyte conditions, and precise control of operational parameters in achieving effective nitrate remediation. The findings contribute valuable insights for both academic research and practical applications, highlighting ECNR’s promise in mitigating nitrate pollution and promoting a healthier nitrogen cycle.
