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.

金属-有机框架的光响应吸附和解吸行为
金属-有机框架(MOFs)具有多孔结构、超大比表面积、丰富的活性位点和比表电荷,是理想的吸附剂。最近,光响应MOFs在环境修复、医疗和人工智能方面的潜在应用引起了人们的极大研究兴趣。本文系统总结了光响应MOFs和MOF基复合材料在光响应吸附/解吸方面的最新进展。介绍了光响应MOFs的制备策略,包括原位合成、合成后修饰和引入客体分子。综述了光诱导结构变化和光响应吸附/解吸的机理。讨论了光响应MOFs的进一步发展前景。通过光照射容易再生光响应MOF基吸附剂在节能、环境友好和可持续性方面具有很高的前景。
