Abstract

Porous materials with photochromic units are currently under investigation as light allows for environmentally friendly and highly energy-efficient control for gas separation and storage, chemical sensing, and drug delivery. In the application of photo-switching materials to CO₂ capture, researchers have tried to endow a diversity of porous materials such as metal-organic frameworks and porous organic polymers with photo-responsive units. This review highlights photochromic units and methods used for different types of photo-responsive adsorbents of CO₂ and some examples of adsorbents with photo-switching properties. These sorbents are also promising for application to direct air capture of CO₂. In particular, the cost of adsorbent regeneration could be reduced by using sorbents with light-induced regeneration. The key purpose of this review is to motivate more research into photo-switching sorbents for CO₂ capture with the control of capture or release by simply switching the light on and off.
