Smart design for CBRN protection by coupling adsorption and photocatalysis: Regeneration adsorbent efficiency – CWAs’ continuous purification

Assessing Detoxification Performance of Metal Hydroxide@Polymer Composites Prepared via Matrix-Incorporation and Spray-Coating Techniques

“…To date, various materials have been developed and tested as potential detoxifying agents toward destruction of organophosphorus CWAs (i.e., DMNP), among which metal oxides have shown promising performances, − owing to their surface Lewis acidity and porosity . For example, a hydroxylated zirconium (Zr) oxide was grafted within graphitized carbon nanofibers and used as nanosponge catalyst to detoxify DMNP.…”

A Miniaturized Method for Evaluating the Dynamic Gas-Phase Adsorption and Degradation of Sarin on Porous Adsorbents at Different Humidity Levels

“…Porous crystalline metal–organic frameworks (MOFs) and other porous adsorbents have attracted great interest over the past decade. These materials have demonstrated both competitive adsorption capacity for nerve agents and the ability to catalyze their hydrolytic degradation. − Recent studies on MOF powders based on zirconium nodes (Zr 6 (μ 3 -O) 4 (μ 3 –OH) 4 ) and various organic linkers have shed light on the factors controlling hydrolysis, allowing OP nerve agents and simulants to be degraded at increasingly impressive rates ( t 1/2 < 1 min). , The rate of catalytic hydrolysis can be enhanced by introducing missing linkers or defect nodes to increase accessibility to Lewis acidic metal sites, enlarging the pore apertures (e.g., by using longer linkers), and/or introducing basic moieties (e.g., NH 2 -groups) into the framework. In accordance with these findings, a recently proposed mechanism suggests that complete catalytic conversion involves several critical and consecutive steps .…”
