The high-energy demand of benzene, toluene, and xylene (BTX) separation highlights the need for improved nonthermal techniques materials. Because their high surface areas, tunable structures, chemical stabilities, metal–organic frameworks (MOFs) are a promising class materials use in more energy efficient, adsorption-based separations. In this work, BTX compounds pore environment UiO-66 were systematically examined using situ infrared (IR) spectroscopy to understand fundamental interactions...
The threat of chemical warfare agents (CWAs), assured by their ease synthesis and effectiveness as a terrorizing weapon, will persist long after the once-tremendous stockpiles in U.S. elsewhere are finally destroyed. As such, soldier civilian protection, battlefield decontamination, environmental remediation from CWAs remain top national security priorities. New approaches for fast complete destruction have been an active field research many decades, new technologies generated immense...
Carbon dioxide (CO2) capture and separation in sorbent materials relies on the interactions that take place between guest molecules topological or chemical features of sorbent. Although researchers have developed an immense library metal–organic framework (MOF) designs, which range shape, size, functionality, a molecular-level understanding how MOF structure functionality affect transport has yet to be fully achieved. In this work, situ infrared spectroscopic techniques, coupled with density...
Developing novel and more efficient filters for chemical warfare agent (CWA) decomposition remains an important challenge modern technology due to the continuous threat those weapons present in event of use. Recently, metal–organic frameworks (MOFs) have attracted attention as potential catalysts nerve decomposition. However, order improve their performance under battlefield conditions, it is crucial understand influence ambient contaminants such carbon dioxide on CWA adsorption Here, we a...
The ever-present threat of the accidental or nefarious release hazardous chemicals on civilian and military personnel highlights need for rapid, standoff detection systems. Our research was motivated by a class hydrogen-bond acidic sorbents that have shown tremendous potential use as preconcentrator materials organophosphorus-based chemical warfare agents (CWA). In this work, series functionalized bisphenol AF (BPAF)-based (HB) were developed with aim providing highly selective rapid-uptake...
Alcoholic and phenolic hydrogen-bond (HB) acidic absorbents activated by fluorine chemistries have been previously developed at the U.S. Naval Research Laboratory elsewhere to augment sorbent HB acidity, reduce basicity target complementary of a wide range hazardous chemicals. A significant limitation sorbents date has propensity for self-association. This intermolecular bonding between molecules hinders sorbate access active acid sites in sorbent, limiting its overall efficacy. Sorbent...
