Sulfonic acid functionalized mesoporous ZSM-5 (SO 3 H-Meso ZSM-5) were prepared by post-grafting of
3-mercaptopropyltriethoxysilane with various loading in the range of 10–50 wt% followed by oxidation
of thiol using H 2 O 2 to generate the corresponding sulfonic acid group.大神帮忙翻译一下

握个爪,你把文献给我发过来,我看看...

Sulfonic acid functionalized mesoporous ZSM-5 (SO 3 H-Meso ZSM-5) were prepared by post-grafting of
3-mercaptopropyltriethoxysilane with various loading in the range of 10–50 wt% followed by oxidation of thiol using H 2 O 2 to generate the corresponding sulfonic acid group. Grafting of organic moieties was evidenced by elemental analysis, 29 Si&13 C-NMR and X-ray photoelectron spectroscopy. The SO 3 H-Meso
ZSM-5 catalyst with improved acidity and mesoporosity exhibited enhanced catalytic activity in acid-catalyzed liquid-phase reaction of 2 ? -hydroxyacetophenone and benzaldehyde compared with non-functionalized mesoporous ZSM-5 (Meso ZSM-5) and functionalized microporous ZSM-5 (SO 3 H-ZSM-5).
Thehigher loading of sulfonic acid functional groups led to higher acidity and consequently resulted in higher yield of products. The catalyst could be reused up to three cycles without significant loss in its catalytic activity这是摘要部分我不知道怎么添加附件就这样发了Sulfonic acid functionalized mesoporous ZSM-5: Synthesis,characterization and catalytic activity in acidic catalysis这是文章的题目发表在Catalysis Today上

磺酸基介孔ZSM-5是这样制备的:先加入3-巯丙基三丁氧基硅烷然后加入质量分数为5%到10%的过氧化氢溶液制出相应的磺酸基。不知道对不对。没制备过,zsm-5不是得有硅铝氧三种元素吗?照这样做得话,怎么没有铝源?或者是没有全部写出。
好好造地球

小弟刚接触催化不太懂文献中确实就这么写的没有铝。

文献应该是ZSM-5催化剂的前驱体已经制备完成要负载磺酸基不知道对不对?
