Abstract: Described herein are compositions and methods relating to molecular cerium-oxide nanoclusters. Described herein are methods of producing cerium-oxide nanoclusters. Described herein are cerium-oxide nanoclusters. Further described herein are cerium-oxide nanoclusters produced by methods as described herein. Methods as described herein can comprise providing a first cerium source, an organic acid, and a solvent; and mixing the cerium source and the organic acid in the presence of a solvent to create a reaction mixture at a temperature and a pressure for a period of time to create a composition of molecular cerium-oxide nanoclusters containing a plurality of molecular cerium-oxide nanoclusters.
