Overlooked impact of surface hydroxylation on the solubility of less-soluble compounds: a case study of CeO2†
Unexpectedly, the solubility of CeO2 nanoparticles (NPs) at 25 °C does not depend on particle size, but is significantly affected by the sample's thermal pre-treatment. The classical interpretation of NPs' solubility proposed by the Gibbs–Thompson or Kelvin equations fails to describe the experimental data on CeO2 solubility obtained in this study. Thermal treatment did not change the samples' morphological characteristics, while slightly affecting NP hydroxylation and local crystallinity. The differences in the solubility of dried and non-treated CeO2 particles were most noticeable at pH < 4, and dissolved cerium concentration was much lower in the case of the dried sample. After prolonged storage (up to 4.5 years) of CeO2 NPs in aqueous media, the solubility of dried samples gradually increased, while for non-treated samples it remained unchanged. Based on the example of CeO2, the dissolution laws of other less soluble nanomaterials should be reconsidered.
期刊介绍：
ACS Applied Materials & Interfaces is a leading interdisciplinary journal that brings together chemists, engineers, physicists, and biologists to explore the development and utilization of newly-discovered materials and interfacial processes for specific applications. Our journal has experienced remarkable growth since its establishment in 2009, both in terms of the number of articles published and the impact of the research showcased. We are proud to foster a truly global community, with the majority of published articles originating from outside the United States, reflecting the rapid growth of applied research worldwide.
