Metal-organic framework is a kind of regular porous material which is self-assembled by metal ion centerorganic ligand framework. I used the metal-organic framework as a templateprecursor to successfully develop a low-cost bimetallic phosphide, which exhibits excellent water splitting hydrogen production performance. The on-site real-time change experiment technology provided by Taiwan Photon Source is a great weapon for real-time detection of active sitesreaction centers during the development of key catalyst materials.
