Abstract

Solid-adsorbent-based temperature swing adsorption (TSA) technology is intriguing in CO₂ capture, and the predominant energy consumption lies in the temperature swing process. Inspired by the self-regulation of lizards, here, we design a solar-radiation-induced adsorption/desorption system, avoiding additional energy supply for the temperature swing process. In this system, adsorbents filled in a reversible quartz device are covered by radiative cooling coating. With the demand of adsorption and desorption, the temperature of adsorbents can be regulated by radiative cooling and solar heating, respectively. Adsorption tests for over 1 year using the metal-organic framework HKUST-1 as an adsorbent demonstrate that the CO₂ working capacity of our system is higher than most industrial TSA with various adsorbents. Furthermore, our system can save more than 80% of the energy input for industrial TSA technologies.
