染料改性 SiO2 的 H2S 气敏性能研究

睿琪 何, 娟 谢

摘要


论文利用石英晶体微天平（QCM）研究了不同粒径二氧化硅（SiO2）对 H2S 气敏性能的影响规律。结果表明，小粒径的 SiO2（微球直径约 75nm）更有利于吸附 H2S 气体。进一步使用染料（甲基橙和亚甲基蓝）对 SiO2 材料进行改性，3种粒径的 SiO2 使用甲基橙改性后对 H2S 的吸附容量较改性前分别有 2.5、2.6 和 4.8 倍的提升，使用亚甲基蓝改性后的 SiO2 材料对 H2S 的吸附容量较改性前分别有 6.8、8.6 和 15.6 倍的提升。最后我们研究了敏感材料对 H2S 气体的吸附机理。
