A pyrene-based metal-organic framework (MOF) NU-1000 was used as a heterogeneous photocatalyst for the degradation of a sulfur mustard simulant, 2-chloroethyl ethyl sulfide (CEES). Using irradiation from a commercially available and inexpensive ultraviolet (UV) light-emitting diode (LED), singlet oxygen (O) is generated by NU-1000 and selectively oxidizes CEES to the nontoxic product 2-chloroethyl ethyl sulfoxide (CEESO). More importantly, this method was tested on the warfare agent sulfur mustard (HD) for the first time using O and a MOF catalyst, and this method proved to be effective in oxidizing sulfur mustard to nontoxic products without forming the toxic sulfone by-product.
一种基于芘的金属有机框架（MOF）NU-1000被用作多相光催化剂，用于降解硫芥模拟物2-氯乙基乙基硫醚（CEES）。利用市售且价格低廉的紫外（UV）发光二极管（LED）发出的辐射，NU-1000产生单线态氧（O），并将CEES选择性地氧化为无毒产物2-氯乙基乙基亚砜（CEESO）。更重要的是，该方法首次使用O和MOF催化剂对战争毒剂硫芥（HD）进行了测试，并且该方法被证明可有效地将硫芥氧化为无毒产物，而不会形成有毒的砜副产物。
