Multi Ball-In-Ball Hybrid Metal Oxides

A straightforward strategy for the synthesis of composition-tunable hybrid metal oxide particles with a unique multi ball-in-ball structure has been demonstrated. The systems are logically formulated and prepared using the following processes: i) coordination polymer particles (CPPs) are prepared using a precipitation method, ii) a cation exchange reaction is used to effect composition change, and iii) a final calcination process of CPPs is use to obtain the metal oxides.
