摘要

直接合成稳定的、具有高缺陷的金属有机框架(MOF)材料在材料科学上是一种挑战，本研究通过一锅水热合成法，基于混合配体诱导策略成功制备出富含结构缺陷的双配体MOF材料(UiO-66-NO

/50BDC). 热重(TGA)定量分析确认其缺陷数为4.02. 高于原始单配体的1.

86. 在氧化降解芥子气模拟物CEES的催化反应中，该MOF材料展现出优异性能，不仅实现了93.3%的高转化率，更重要的是对无毒亚砜产物(CEESO)的选择性超过99%，兼具高活性与高选择性. 其性能显著优于4种单配体MOF (UiO-66、UiO-66-NO

、HKUST-1及MIL-88A). 催化活性的显著提升，主要源于丰富的路易斯酸位点(由结构缺陷产生)、因缺陷导致孔道扩张进而增强的反应物/产物扩散以及较大的比表面积.

Abstract

The direct synthesis of stable metal-organic frameworks (MOFs) with high defect concentrations remains a challenge in materials science. In this work

we successfully prepared mixed-ligand MOF with structural defects

denoted as UiO-66-NO

/50BDC

via

a one-pot hydrothermal synthesis based on a mixed-ligand induction strategy. Quantitative TGA analysis confirmed a defect number of 4.02 per Zr

cluster

which was substantially higher than that of the pristine single-ligand MOF (1.86). In the catalytic oxidation degradation of the sulfur mustard simulant CEES

this MOF material exhibited outstanding performance

achieving not only a high conversion rate of 93.3% but also a selectivity exceeding 99% for the non-toxic sulfoxide product (CEESO). Its performance was significantly superior to that of four single-ligand MOFs (UiO-66

UiO-66-NO

HKUST-1

and MIL-88A

). The remarkable enhancement in catalytic activity was primarily attributed to the abundant Lewis acid sites (generated by structural defects)

enhanced diffusion of reactants/products resulting from defect-induced pore expansion

and the large specific surface area.
