Composite System of Ag Nanoparticles and Metal–Organic Frameworks for the Capture and Conversion of Carbon Dioxide under Mild Conditions

Abstract

The materials Ag@MIL-100(Fe) and Ag@UIO-66(Zr) are obtained for the capture and transformation of CO₂ into alkynyl carboxylic acids, which are environmental friendly, facile to synthesize, and exhibit excellent efficiency and reusability. The influence on the catalytic activity of such Ag@MOF systems by metal-organic frameworks' (MOFs) surface area, thermal, and chemical stability, especially the acid-base characteristics of the pores, are compared and discussed systematically.
