报道了用直流磁控溅射法制备氧化铜（CuO）纳米粒子，并用于吸附降解化学战剂芥子气（HD）的模拟物2-氯乙基乙基硫醚（CEES）。采用XRD、TEM、FE-SEM、N2-BET、FT-IR和TGA等手段对合成的纳米CuO进行了表征。从XRD图谱计算的平均粒径被认为是7 nm的沉积和变化后退火到86 nm。还通过TEM分析计算粒度。与文献报道的相比，发现颗粒的表面积（110-36 m2/g）显著增加。CEES的降解动力学研究了CuO纳米粒子，发现直流溅射CuO纳米粒子对CEES具有上级去污性能。反应似乎是一级反应，速率常数（k）和半衰期（t1/2）值分别在0.434-0.134 h− 1和1.59-5.17 h范围内。通过GC-MS和FT-IR对反应产物进行了表征，揭示了水解反应在CEES去污中的作用。
We report the synthesis of copper oxide (CuO) nanoparticles by dc magnetron sputtering for adsorptive degradation of 2-chloroethyl ethyl sulfide (CEES), a simulant of well-known chemical warfare agent sulfur mustard (HD). The synthesized CuO nanoparticles were characterized by XRD, TEM, FE-SEM, N2-BET, FT-IR and TGA. The average particle size calculated from XRD pattern was found to be 7 nm for as-deposited and varied up to 86 nm after postannealing. The particle size was also calculated through TEM analysis. The surface area of the particles (∼110–36 m2/g) is found to be enhanced significantly in comparison with reported in the literature. Degradation kinetics of CEES was investigated over the CuO nanoparticles and it was found that dc sputtered CuO nanoparticles give superior decontamination properties against CEES. The reactions seemed to be first order with rate constant (k) and half-life (t1/2) values in the range of 0.434–0.134 h−1and 1.59–5.17 h respectively. The reaction products were characterized by GC–MS and verified through FT-IR. The data reveal the role of hydrolysis reactions in the decontamination of CEES.
