Kilogram‐Scale Water‐Mediated Exfoliation Strategy for Defect‐Free Single‐Layer MXene Nanosheets

ABSTRACT Single‐layer MXene nanosheets have garnered immense attention for their remarkable functional versatility; however, their ultimate performance and application potential are fundamentally limited by their intrinsic quality. Traditional high‐yield methods for MXenes typically involve high‐energy mechanical input, often introducing a substantial density of defects, which inevitably creates the trade‐off between quality and scalability. Herein, we present a water‐mediated exfoliation strate
