Abstract
This work demonstrates the straightforward, one-pot hydrothermal preparation of 1D core-shell nanocables (NCs) by utilizing glucose simultaneously as a green reducing agent and a carbon precursor. The resulting high-aspect-ratio NCs exhibit a robust core-shell geometry that induces a strong synergistic interaction between the tellurium core and the hydrothermal carbon (HC) shell. This synergy significantly enhances panchromatic light harvesting, yielding exceptional absorption capabilities in the near-infrared spectrum. By integrating these structurally well-defined NCs into a 3D melamine foam (MF) matrix, we fabricated highly efficient photothermal sponges. Upon exposure to simulated 1 sun irradiation, the NCs/MF sponge attained a remarkable surface temperature of 77.8 °C. Consequently, the system delivered an outstanding water evaporation flux of 1.51 kg m⁻² h⁻¹ alongside a solar-to-vapor conversion efficiency of 97.5%. Ultimately, this study provides a highly effective and scalable pathway for designing high-performance nanomaterials tailored for advanced solar-thermal energy conversion and clean water generation.
