Summary: Metal-organic frameworks (MOFs) have limitations in the hydrolysis of nerve agents due to the stable bridging configuration between the hydrolyzed products and the MOF nodes. This study presents two copper single atom-modified UiO-66 MOFs, which exhibit similar reactivity to the native MOF under aqueous conditions, suggesting the influence of the copper coordination environment on product inhibition.

Summary: The development of effective protection against exposure to chemical warfare agents relies on studying the adsorption of these agents on capturing materials. Metal-organic frameworks have shown promise in capturing and degrading sarin and simulant substances. Molecular simulations were performed to study the adsorption of sarin and three simulants on selected MOFs, revealing common mechanisms among efficient adsorbents and the ability of simulants to mimic them. These findings can guide the selection of suitable simulant compounds for studying CWA adsorption and the synthesis of efficient MOFs for capturing organophosphorus compounds.

Summary: A novel aminal-linked porphyrinic COF, Por-Aminal-COF, was synthesized and characterized. It exhibited excellent photocatalytic activity for the detoxification of sulfur mustard simulant with a much shorter half-life compared to the traditional imine-linked Por-COF. The superior photocatalytic performance of Por-Aminal-COF was attributed to its aminal linkages, which facilitated the intersystem crossing process and enhanced triplet-state generation efficiency.

Summary: This study aims to develop highly efficient bifunctional catalysts for the simultaneous detoxification of nerve agent and blister agent, two of the deadliest chemical warfare agents. By introducing two porphyrin-based ligands (TCPP and PPIX) into two-dimensional ultrathin metal-organic framework materials (MOLs), the catalytic activity of the MOLs for nerve agent and blister agent simulants was investigated. The results showed that TCPP-functionalized MOL exhibited the highest catalytic activity for the degradation of blister agent simulant under solar light.

Summary: In this study, Co atomically dispersed on three-dimensional networks of N-doped graphene (3DNG) was prepared and characterized as ACo/3DNG composite. The atomically dispersed Co and enriched Co-N species provided ACo/3DNG with unique catalytic activity for hydrolysis of organophosphorus agents (OPs), and the network structure and super-hydrophobic surface of 3DNG ensured excellent physical adsorption capacity. Therefore, ACo/3DNG showed promising potential for the removal of OPs pesticides from water.
