“…37 As a new family of MOF material, MOF-on-MOF holds excellent potential in efficiently fabricating a multishelled hollow metal oxide composite using competitive oxidation of multiple MOFs. 38 In our study, TSH ZMO/CMO composite can be synthesized via simple calcination of solid Mn-MIL-100@ZIF, leading to uniform, well-dispersed, and stable metal oxide nanoparticles with heterojunctions, rough surface, and sharp corners. Furthermore, the shell number of ZMO/CMO can be controlled by changing the heating rate.…”
