An aqueous one-pot self-templating synthesis method to prepare highly uniform ZIF-67 hollow spheres (ZIF-67-HS) and their transition metal-doped derivatives (M/ZIF-67-HS, M = Cu and/or Zn) was developed. Extension of this approach to another important class of MOFs (metal carboxylates; e.g., HKUST-1) and facile design of derived nanostructures with complex architectures were also achieved.
