Generation of Nanoparticle, Atomic-Cluster, and Single-Atom Cobalt Catalysts from Zeolitic Imidazole Frameworks by Spatial Isolation and Their Use in Zinc-Air Batteries
TL;DR: The spatial isolation of cobalt species on the atomic scale is reported by tuning the zinc dopant content in predesigned bimetallic Zn/Co zeolitic imidazole frameworks (ZnCo-ZIFs), which led to the synthesis of nanoparticles, atomic clusters, and single atoms of Co catalysts on N-doped porous carbon.
Journal ArticleDOI
Macroscopic Spontaneous Polarization and Surface Oxygen Vacancies Collaboratively Boosting CO2 Photoreduction on BiOIO3 Single Crystals
TL;DR: The synchronous promotion of bulk and surface separation of photoinduced charges for prominent CO2 photoreduction by coupling macroscopic spontaneous polarization and surface oxygen vacancies of BiOIO3 single crystals is reported.
