National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

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 andsoft 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.
