제목 Controllable Synthesis and Catalytic Activities of Gold Multipod Nanoparticle Cores and NMOF-Derived Shell Nanohybrids
초록 We report a facile fabrication of gold multipod nanoparticles (GMNs) embedded within cobalt sulfide nanocage. Specifically, the as-prepared GMN cores- ZIF-67 shell (GMN@ZIF-67) nanostructures are precursors for the preparation of unique nanohybrids composed of multiple GMNs and cobalt sulfide (GMN@CoxSy) nanocages. This is an unusual example how anisotropic noble metal nanoparticle cores-inorganic cage-like shells nanohybrids derived from NMOFs can be prepared. The insertions of GMNs into cobalt sulfide nanocages can result in a substantially higher OER activity of GMN@CoxSy nanocages (345 mV) compared with those of GMNs (617 mV) and CoxSy nanomaterials (418 mV) at the current density of 10 mA cm-2. The enhanced OER performance of GMN@CoxSy nanocages is mainly attributed to the synergistic effect between the GMN cores and cage-like cobalt sulfide shells.
