Zusammenfassung:Disclosed in certain embodiments are closed-cell metal oxide particles and methods of preparing the same. In at least one embodiment, a closed-cell metal oxide particle comprises a metal oxide matrix defining an array of closed-cells. Each closed-cell encapsulates a media-inaccessible void volume. The outer surface of the closed-cell metal oxide particle is defined by the array of closed-cells.
