A lot of information on nanomaterial synthesis and properties are well-documented in the literature. However, we often ignore how these nanostructures originate using a variety of precursors via wet chemical routes. While working on nanocerium oxide (CNP), an important material in catalysis, we find a lot of differences in their properties when prepared using a variety of precursors using the same wet chemical synthesis. Through our ongoing research, we have recently documented the unique biomedical usages of CNP. Herein, we have tested our hypothesis that surface chemistry and antioxidant properties of CNPs are affected by the presence of counterions from various cerium salts used in the synthesis. The rearrangement of surface atoms was observed with sub-angstrom probing suggesting the importance of surface chemistry in tuning the CNPs. As a result, physicochemical properties of these CNPs were found to be affected by the anions of the precursor salts. In this talk, we present some of the mechanistic understanding of our recent findings.
