제목 Kinetic-Controlloed Formation of Core–Shell MOF-derived CoP Nanoparticle-Embedded N-Doped Carbon Nanotube Hollow nanocube for Efficient Overall Water Splitting
초록 Herein, we report a novel hybrid nanostructure with CoP nanoparticles (NPs) embedded in a N-doped carbon nanotube hollow Nanocube through a pyrolysis–phosphidation strategy derived from core–shell ZIF-67@ZIF-8. Metal–organic frameworks (MOFs) are constructed from two kinds of metal ions, while still remaining their original topologies. Due to distinct reaction kinetics during MOF formation, partial distribution of different metals within a single MOF crystal can lead to sophisticate nanostructures by adding the two metals in sequence. Specifically, when Co2+ is added first, ZIF-67@ZIF-8/67 core–shell nanocrystals are achieved with tunable core/shell thickness ratio depending on the time intervals. This strategy might open an avenue to synthesize various hollow yolk–shell nanoreactors with controllable structures and enhanced catalytic performances.
