A Study on the Improvement of the Photothermal Characteristics of the Adsorbent for Sorption-Based Atmospheric Water Harvesting Driven by Solar

Facing the global freshwater resource crisis, using solar energy to produce fresh water resources in an environmentally friendly way, sorption-based atmospheric harvesting driven by technology has attracted increasingly more attention. In current research, adsorbent MOF-801 advantages of a high adsorption capacity and is suitable for fields with wide range humidity. However, strong interaction between molecules conducive rapid moisture absorption, but at same time, needs higher heat achieve regeneration, which restricts practical application adsorbent. Based on principle that carbon materials can improve photothermal conversion performance adsorbent, this paper prepared three composite adsorbents different materials, characterized structure morphology each compared effects Among them, characteristics MOF-801/CNT proposed are most significantly improved. The experiment shows MOF-801/G, increased 30%, desorption speed 50%. It maximizes withdrawals over period time arid environments.
