Synthesis and characteristics of ionic liquid-implanted HKUST-1 metal-organic frameworks for transforming heat into extraordinary water transfer

This paper proposes ionic liquid (IL)-embedded HKUST-1 metal-organic frameworks (MOFs) to boost water transfer for transforming waste heat into work. First, the parent HKUST-1 is synthesized and encapsulated with different types of ionic liquids and various embedment ratios. Second, the parent and m...
