摘要 本文通过考察合成后盐处理对介孔材料MCM-41的结构影响,发现添加铵盐和调节pH值可以提高在碱性合成条件下得到的介孔MCM-41的孔道有序度,并保持相当的稳定性;同时发现换用钠盐处理有相反的破坏作用。利用XRD、TEM、TG-DTA技术对上述现象进行了研究和分析,认为不同离子对于静电环境的改变和对氢键形成的促进作用是造成该影响的主要原因。 The effects of salt-treatments on the structure and the stability of MCM-41 mesoporous material were investigated.It was found that,by adding ammonium salts and adjusting pH during the post-synthesis to alkalescently synthesized MCM-41,the regularity of the pore was improved dramatically and the stability of the mesostructure was retained;conversely,they were diminished by adding sodium salts.The results were studied by analyzing the samples using X-ray diffraction(XRD),Transmission electron microscopy(TEM),Differential Thermal Analysis-Thermal Gravimetry(DTA-TG).The change of the electrostatic surrounding and the formation of hydrogen bonds caused by different ions were confirmed to be the main factors.
