不同於一般傳統液態消除劑，固態金屬氧化物因具有高比表面積、良好的熱穩定性及物理、化學性質等特點，並且還兼具催化劑的角色，可藉由進行水解、氧化與催化等化學反應，降解去除化學毒性物質之危害性。有鑒於此，本研究嘗試以奈米級多孔性吸附材Al2O3或Al2O3/Na2SiO3（0.5wt.%~2.5wt.%）為擔體，藉由臨溼含浸法承載p型半導體Ag2O（1wt.%~10wt.%）奈米粒子，探討金屬氧化物於添加不同比例的濃度對降解模擬劑2-氯乙基乙基硫醚（C2H5SCH2CH2Cl，2-CEES）催化反應的影響。並利用化學還原法，將Ag2O還原成Ag金屬，探討其對催化反應可能造成的影響。研究應用BET、XRD、TEM、GC-PFPD及GC-MS來觀察與辨別這些催化反應，同時並進行材料結構與微結構的分析鑑定工作。
由表面積測定儀(BET)結果，經臨濕含浸Na2SiO3 及Ag2O的各系列觸媒，孔體積會隨著Ag2O或Na2SiO3含量的增加而下降，而平均孔徑則隨之上升，但不顯著。由氣相層析質譜儀(GC-MS)分析結果顯示，2.5%Ag2O/0.5%Na2SiO3/Al2O3具有降解催化的效果。催化反應後的產物為無毒之2-（乙硫基）乙醇(CH3CH2SCH2CH2OH)和2-（乙硫基）乙酸(CH3CH2SCH2COOH)。證實Ag2O不僅只扮演催化劑的角色，更能與水及Na2SiO3/Al2O3擔體產生協同效果來增加毒化物降解效能。由氣相層析儀（GC-PFPD）的分析結果得知，在溶於異丙醇的2-chloro ethyl ethyl sulphide (C2H5SCH2CH2Cl, 2-CEES)溶液中加入2.5 %的Al2O3或Al2O3/Na2SiO3進行催化反應，於15分鐘內的消除率可達82 %。顯示添加少量的Na2SiO3對催化反應即有極大的提升效果，且添加劑量濃度也能以計算得知，而Ag2O的添加更能大幅提升降解2-CEES之催化能力。顯示這些由電洞所構成的p型半導體Ag2O在啟動催化反應中扮演著不可或缺的角色。

Different from the traditional liquid state decontamination, because solid metal oxide is high than characteristics such as surface area, good heat stability and physics, chemical property,etc., and the role with catalyst, by applying and taking the chemical reaction of hydrolyzing, oxidizing and catalyzing etc. In order to degrade or remove the harmfulness of the toxic material of chemistry, and more important , have high affinity to personnel,apparatus and environment, will not cause and damage and pollute. p-type Ag2O （1wt.%~10wt.%）semiconductor nanoparticle-loaded Ag2O or Na2SiO3/Ag2O（0.5wt.%~2.5wt.%） powders used for detoxicating the surrogate of sulfur mustard of 2-chloro ethyl ethyl sulfide (C2H5SCH2CH2Cl, 2-CEES) were investigated. Different amounts of Ag2O and Na2SiO3 on catalyst supports were evaluated. And using chemical reduction method, sodium borohydride as reductant, Ag2O reduced to Ag metal, to explore its catalytic reaction may be the impact. Studying employs Brunauer-Emmett-Teller (BET)、X-ray diffraction (XRD)、Transmitted Electron Microscope (TEM)、Gas chromatography with a pulsed flame photometric detector (GC–PFPD) and gas chromatography coupled with a mass spectroscopy (GC–MS) were used to monitor and identify the catalytic reactions, together with reaction products analysis.
The results of the surface area (BET) analysis, showed that the wetting impregnated Na2SiO3 and Ag2O each series of catalyst, the pore volume will decrease with the increase of Ag2O or Na2SiO3 content, while the average pore diameter will rise, but not significant.
The results of gas chromatography-mass spectrometry (GC-MS) analysis, showed that 2.5% Ag2O / 0.5% Na2SiO3 / Al2O3 had the catalytic effect of degradation. The products after the catalytic reaction are non-toxic 2-(ethylthio)ethanol (CH3CH2SCH2CH2OH) and 2- (ethylthio) acetic acid (CH3CH2SCH2COOH). Confirmed Ag2O not only act as a catalyst, but also with water and Na2SiO3 / Al2O3 support synergistic effect to increase the toxicity of toxic compounds.
The results of the Gas chromatography (GC-PFPD) analysis, 2.5% Al2O3 or Al2O3 / Na2SiO3 was added to the solution of 2-chloroethyl ethyl sulphide (C2H5SCH2CH2Cl, 2-CEES) dissolved in isopropanol Response, within 15 minutes the elimination rate of up to 82%. By adding a small amount of Na2SiO3 on the catalytic reaction that has a great effect, and the concentration can be calculated to calculate the additive, and Ag2O addition can greatly enhance the catalytic capacity of 2-CEES degradation. The electronic holes dominating in p-type Ag2O is proposed to provide the key component and to initiate the catalytic reactions. The electronic hole-based detoxication mechanism is proposed.
