摘　　要：氢氧化锆[Zr(OH)_(4)]被认为是一种具有潜力的化学战剂降解催化剂,常规的Zr(OH)_(4)粉末难以负载且比表面积小。设计并制备了一种具有丰富微孔结构的Zr(OH)_(4)纳米颗粒,其比表面积可达521.493 m^(2)/g,平均孔径为0.461 nm。在此基础上开发了一种新方法,采用多孔Zr(OH)_(4)在纳米纤维上原位生长构筑超高比表面积ZrCl_(4)/PA-6@Zr(OH)_(4)纳米纤维面料。Zr(OH)_(4)纳米颗粒分散均匀,负载稳定,表现出优异的芥子气模拟剂CEES催化降解性能。在常温常湿条件下,CEES的降解效率超过90%。Zirconium(Ⅳ)hydroxide[Zr(OH)_(4)]is considered as one of the most potential catalysts for chemical warfare agent degradation.However,conventional Zr(OH)_(4)powder is difficult to load and possess a small specific surface areas.A Zr(OH)_(4)nanoparticle with rich microporous structure is designed and prepared,with an ultra-high specific surface area of 521.493 m/g and an average pore size of 0.46lnm.On this basis,a novel method is developed to construct ultra-high specific surface area ZrCl_(4)/PA-6@Zr(OH)_(4)nanofiber fabric by in-situ growth of porous Zr(OH)_(4)nanoparticles on nanofibers.The uniformly dispersed and stably loaded Zr(OH)_(4)nanoparticles show excellent catalytic degradation performance of mustard gas simulator CEES.The degradation efficiency of CEES can reach more than 90%under normal temperature and humidity.
