Metal-organic framework (MOF) forms one to three-dimensional crystal structure by strong bonding between metal clusters and organic ligands. MOF is a new class of porous crystalline materials with high crystallinity, micro/mesopores, and a large specific surface area. Zr-MOF-808 is composed of Zr-SBUs connected to six 1,3,5-benzenetricarboxylate (BTC) linkers to form a 3D porous framework containing two different types of pores. These two pore modes increase mass transfer for reactions, suggesting its potential application as electrocatalyst support. In this study, we synthesized micron-sized Zr-MOF-808 granules by spray drying Zr-MOF-808 crystals of various sizes. Spray drying is the process of converting a suspension containing fine particles into granules composed of fine particles. In the synthesis process, Pt is loaded through spray drying so that a large amount of metal can be loaded into the granule with a relatively small amount of Pt. |
