Zirconium Hydroxide Nanoparticles for Toxic Chemical Sequestration: Environmental Implications on Surface Reactivity, Capacity, and CWA Decomposition
Abstract
The objective of this project was to understand how operando conditions, such as common atmospheric contaminants and environmentalconditions like light and temperature, affect the adsorption and decomposition mechanisms of CWAs and CWA simulants on zirconium hydroxide, a promising sorbent and decomposition material. Decomposition of simulants and CWAs were studied primarily using ambient-compatible and soft characterization methods such as ATR-IR, DRIFTS, microbreakthrough, and XPS. Theoretical calculations provide experimental support and insight into most likely decomposition pathways, adsorbate stability, and potential surface poisoning resulting from decomposition products.
