Abstract
Metal–organic frameworks (MOFs) are ideal adsorbents because of their porous structure, ultra-large specific surface area, abundant active sites, and specific surface charge. Recently, light-response MOFs have received considerable research interests regarding their potential applications in environmental remediation, medical treatment, and artificial intelligence. This review systematically summarizes the recent progress of light-response MOFs and MOF-based composites for light-response adsorption/desorption. The fabrication strategies of light-response MOFs, including in situ synthesis, post-synthesis modification, and introduction of guest molecules, are presented. The mechanisms of light-induced structural change and light-responsive adsorption/desorption are summarized. The prospects for further development of light-response MOFs are discussed. The facile regeneration of light-response MOF-based adsorbents by light irradiation is highly promising for energy saving, environmental friendliness, and sustainability.
