Abstract

Exigency in search of an ideal candidate for an effective detoxification of chemical warfare agents is still continuing. Zirconium-based Metal-organic Framework (MOF) UiO-66 has shown a significant detoxification of such toxic chemicals owing to its tunable physio-chemical properties and profuse catalytic sites. In this context, a series of UiO-66 MOFs synthesized by tuning the acidity constant (p ) and concentration of the modulator, synthesis temperature and water molecules was tested for their detoxification efficiency against the simulant 'methyl-paraoxon' at room temperature. Amongst, HCl modulated UiO-66 across the considered synthesis temperature have shown competent catalytic performance in virtue of defects generation within its structure. In addition, the role of catalytic features of UiO-66 obtained by tailoring its defects in enhancing the degradation efficiency has been systematically investigated. The detoxification efficiency of 98.5% with a half-life time of 0.23 min has confirmed the effectiveness of engineered defects in enhancing the catalytic activity of UiO-66 in detoxifying the identified simulant.

摘要

寻找能够有效解毒化学战剂的理想候选物的迫切需求仍在持续。基于锆的金属有机框架（MOF）UiO-66因其可调节的物理化学性质和丰富的催化位点，已显示出对这类有毒化学物质的显著解毒效果。在此背景下，通过调节酸度常数（p）、调节剂浓度、合成温度和水分子，合成了一系列UiO-66 MOF，并在室温下测试了它们对模拟物“甲基对氧磷”的解毒效率。其中，在考虑的合成温度范围内，HCl调节的UiO-66因其结构中产生的缺陷而表现出良好的催化性能。此外，还系统地研究了通过调整UiO-66的缺陷所获得的催化特性在提高降解效率方面的作用。98.5%的解毒效率和0.23分钟的半衰期证实了工程缺陷在增强UiO-66解毒所鉴定模拟物的催化活性方面的有效性。
