With the rapid advancement of wearable electronics, demand for efficient portable power supplies has become increasingly urgent. Thermoelectric materials, which can directly convert heat, such as body into electricity, offer a promising avenue sustainable energy supplementation. However, achieving high thermoelectric performance in flexible materials suitable heat harvesting remains significant challenge. Here, we introduce strategy synergistically tuning surface oxygen defects and optimizing microstructures low-dimensional semiconductor resulting flexible, ammoniated dual-transition metal carbide o-MXene N-Mo2TiC2Tx with enhanced properties. Theoretical experimental analyses reveal that high-temperature ammoniation produces low-oxygen-functionalized surface, reduces interlayer spacing, minimizes defect density, thereby significantly increasing electrical conductivity. Nitrogen atoms incorporated at nanosheet terminals further increase electron density near Fermi level, an Seebeck coefficient. Consequently, films treated 900 K achieve conductivity 1.03 × 104 S m-1, coefficient -27.8 μV K-1, factor 7.99 μW m-1 K-2 room temperature, nearly 1.2-fold higher than untreated while retaining excellent flexibility. Moreover, generator constructed from these voltage 1.4 mV under temperature gradient approximately 12 between human skin ambient air, underscoring its capacity low-grade thermal energy. These findings establish paradigm development high-performance paving way next-generation industrial applications.
