以大孔容的均匀中孔炭气凝胶为原料，采用模板法合成了具有均匀中孔结构的ZSM-5整体材料（meso-ZSM-5）。通过N2吸附测定的孔径分布显示存在平均孔宽度为11 nm的中孔和平均孔宽度为0.51 nm的微孔。场发射扫描电子显微镜观察显示存在均匀的介孔。X-射线衍射和FT-IR结果表明，合成的介孔ZSM-5具有高度结晶的ZSM-5结构。
A ZSM-5 monolith of uniform mesopores(meso-ZSM-5) was synthesized with the template method using carbon aerogel of uniform mesopores of great pore volume. The pore size distribution determined by N2 adsorption showed the presence of mesopores with an average pore width of 11 nm and micropores with an average pore width of 0.51 nm. Field emission scanning electron micrograph observation revealed the presence of uniform mesopores. X-ray diffraction and FT-IR provided evidence that the synthesized meso-ZSM-5 monolith has a highly crystalline ZSM-5 structure.
