Hydrovoltaic power generation, which harnesses ambient water via solid–liquid interface interactions, offers a green pathway for low-grade energy harvesting. However, conventional carbon-based materials used in such systems often rely on petrochemical-derived precursors, limiting the scalability and environmental sustainability. Herein, we report a novel hydrovoltaic generator (CCHG) that fabricated with the low-cost and conductive coal-based nanocarbon (CCN). The CCN is uniformly deposited on the filter paper to form a water-permeable interface, enabling the directional water transport and evaporation-driven ion diffusion. The resultant CCHG device exhibits a voltage output of 0.53 V and a current of 62 μA with only 50 μL of water under ambient conditions. Integration of multiple units in series or parallel delivers up to 2.1 V and 240 μA, sufficient to drive the power commercial electronics such as LED arrays and timers.

Advanced techniques including synchrotron-based wide-angle X-ray scattering (WAXS), microbeam WAXS (μ-WAXS), spherical aberration-corrected transmission electron microscopy (SA-TEM), electron energy loss spectroscopy (EELS), Raman spectroscopy, small-angle X-ray scattering (SAXS), and positron annihilation lifetime spectroscopy (PALS) have been employed to assess crystallite size, orientation, skin-core microcrystalline evolution, radial distribution of sp<sup>2</sup> hybridized carbon, and micropore morphology across different length scales. Results demonstrate that N-CF1, with its homogeneous skin-core structure, high graphitization, dense and aligned microcrystallites, and minimal defect density, exhibits superior tensile strength. N-CF2, while less crystalline, maintains a relatively balanced radial structure with higher sp<sup>2</sup> carbon content, facilitating effective stress transfer despite partial disorder.

The high-value-added utilization of rare earth modification offers a promising approach for this need.

Here, we develop a promising rare earth (La)-induced two-dimensional (2D) MXene-derived multiscale, dual-phase dielectric TiO<sub>2</sub> strategy.

This strategy effectively modulates the dielectric behavior of MXene/PCN NFs and promotes the formation of 0D/1D/2D multilevel heterogeneous interfaces, achieving lightweight, broadband, and highly efficient EMW absorption properties, with a reflection loss (<em>R</em><sub>L</sub>) value of −61.55 dB and a wide effective absorption bandwidth (EAB) of 5.7 GHz at thin thickness of 1.95 mm. Furthermore, this strategy was achieved through a synergistic electrospinning and thermal treatment process, effectively embedding 0D TiO<sub>2</sub> nanoparticles, La-based species, and 2D MXene nanosheets into 1D PCN NFs. Consequently, favorable interface polarization, conduction loss, and dipole polarization contribute to the outstanding radar stealth properties of the PCN/MXene-La composite.
