@article { , title = {Potential photo-switching sorbents for CO2 capture – A review}, 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.}, doi = {10.1016/j.rser.2022.112079}, eissn = {1879-0690}, issn = {1364-0321}, journal = {Renewable and Sustainable Energy Reviews}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://hull-repository.worktribe.com/output/3917809}, volume = {158}, keyword = {CO2 capture, Sorbent regeneration, Photoresponsivity, Photo-switch, Direct air capture, Photochromic compounds}, year = {2022}, author = {Qiao, Yuanting and Bailey, Josh J. and Huang, Qi and Ke, Xuebin and Wu, Chunfei} }
