Critically examine current progress, cathode mechanisms, and engineering challenges in scaling electrocatalytic and bioelectrochemical nitrate reduction technologies for water treatment.
Review of fundamental cathode reaction mechanisms and catalysts targeting complete selectivity to harmless dinitrogen gas.
Evaluation of reactor design principles for translating benchtop electrochemical cells into practical water treatment flow systems.
Assessment of emerging bioelectrochemical hybrid architectures for energy-efficient environmental denitrification.
Electrocatalysis provides a clean, chemical-free alternative to bacterial denitrification, but achieving 100% selectivity toward dinitrogen gas over intermediate pollutants remains difficult.
Scaling electrochemical reactors requires overcoming severe mass transport bottlenecks and energy efficiency losses to compete with traditional water purification methods.
