Structure Tuning of Hafnium Metal–Organic Frameworks through a Mixed Solvent Approach
Crystals, 2022 The recent development of water-stable metal–organic frameworks (MOFs) has significantly broadened the application scope of this emerging type of porous material. Structure tuning of hafnium MOFs is less studied compared with zirconium MOFs. In this work,
