A sacrificial template strategy is developed for the synthesis of yolk–shell Au@ZIF‐8 nanoreactor. The Au@ZIF‐8 nanoreactor possesses single‐crystalline metal‐organic framework (MOF) shell with intrinsic monodisperse micropores and introduced macropores. In each of the macropores, one Au NP is encapsulated to form a nanoreactor unit. The quantity of the reactor units in the MOF shell can be readily...
The capacity of anode materials plays a critical role in the performance of lithium‐ion batteries. Using the nanocrystals of oxygen‐free metal‐organic framework ZIF‐67 as precursor, a one‐step calcination approach toward the controlled synthesis of CoO nanoparticle cookies with excellent anodic performances is developed in this work. The CoO nanoparticle cookies feature highly porous structure composed...
Hierarchical ZnO hollow spheres (400–500 nm in diameter) consisting of ZnO nanoparticles with a diameter of approximately 15 nm have been successfully prepared by a facile and rapid sonochemical process. The formation of hierarchical ZnO hollow spheres is attributed to the oriented attachment and subsequent Ostwald ripening process according to time‐dependent experiments. The as‐prepared ZnO hollow...
