Abstract

Localized surface plasmon resonance (LSPR) shows great promise in optoelectronic devices, solar steam generation, and medical treatment owing to its strong enhancement of light-matter interactions. Herein, for the first time, 1D-2D metallic MWCNTs and HfTe₂ van der Waals (vdW) heterostructure are used for demonstrating the LSPR to enhance the temperature of a solar absorber. The proposed vdW heterostructure is synthesized by a facile self-grown hydrothermal method and grown on top of a copper (Cu) foam. The HRTEM image and EDS spectrum confirm the formation of the vdW heterostructure on the Cu foam. The synergic effect of Te-based TMD with MWCNT provides a broadband absorbance of approximately 92% weighted by the standard air mass 1.5 global solar spectrum and takes full advantage of LSPR to confine heat in a small area. Moreover, the ultrathin nature of MWCNT endows them with the super permeability of water vapor. The solar-driven steam generation performance of the prepared vdW heterostructure demonstrates an excellent evaporation efficiency of 87.43% and an increment of the surface temperature to 79.8 °C in less than 20 mins under 1 kWm^–2 solar illumination. Therefore, the proposed vdW heterostructure can be realized in high-temperature steam generation applications.
