摘要:
在蒙脱石的层间域插入季铵盐和正硅酸乙酯。通过水热控制和pH调节使正硅酸乙酯围绕季铵盐胶束水解形成二氧化硅。通过煅烧去除季铵盐胶束, 形成蒙脱石多孔材料。将通过质子化和超声处理的纳米级石墨相氮化碳(g-C3N4)负载到多孔蒙脱石多孔材料孔道结构中。通过扫描电镜(SEM)表征了其表面形貌、 颗粒大小和微观结构; 利用物理氮气吸附-脱附表征其孔道结构; 用傅里叶变换红外(FT-IR)表征了表面的官能团; 通过X-射线衍射仪(XRD)分析其有序晶体结构和层状结构。通过对水相中罗丹明B的降解研究其光催化性能。实验结果表明, 负载纳米级g-C3N4的蒙脱石多孔材料具有优异的光催化降解有机物的能力。
Abstract:
Quaternary ammonium salt and tetraethoxysilane(TEOS)were intercalated into interlayered regions of montmorillonite(MMT)by catonic exchange and solvation. The hydrothermal treatment and pH adjust achieved hydrolysis of TEOS around molecular sieve of quaternary ammonium salt. The porous MMT was finally obtained by the removal of quaternary ammonium salt. The bulk g-C3N4 was treated through protonation and ultrasonic dispersion to form the exfoliated g-C3N4 sheets in nanosize. This exfoliated g-C3N4 sheets were loaded onto the obtained porous MMT. The micro-structure of materials were characterized by scanning electron microscopy(SEM). The porous structure was also characterized through the N2 adsorption-desorption isotherms. The functional groups on the surface were characterized by Fourier transform infrared(FT-IR). The ordered crystalline and layered structure were characterized by X-ray diffraction(XRD). The photocatalytic performance of the obtained composites was also investigated. The results show that the composite materials have excellent photocatalytic degradation properties towards organic matter.
