Excessive accumulation of nitrate (NO3-) can lead to eutrophication and ecological degradation, while also posing potential hazards to human health. The conventional Haber-Bosch process for ammonia synthesis, while effective, comes with a heavy environmental toll due to its energy consumption and greenhouse gas emissions. Fortunately, electrocatalytic nitrate reduction (NO3RR) offers a greener alternative, converting nitrates into nitrogen and ammonia, thus curbing environmental pollution while enabling ammonia recycling. MXene, characterized by its high conductivity, large specific surface area, and abundant surface functional groups, emerges as a promising catalytic material for NO3RR applications. This review offers an in-depth investigation into the application of MXene-based materials in NO3RR, elucidating strategies to enhance MXene catalytic efficiency through surface functionalization, defect engineering, and composite material synthesis. The challenges and future research directions for MXene in NO3RR are outlined. The aim is to provide a theoretical framework and practical guidance for the design and improvement of NO3RR catalysts, with the goal of enhancing their reaction efficiency and sustainability.
