Mesoporous Y-type zeolite (MYZ) was prepared by an acid and base treatment of commercial Y-type zeolite (YZ). The mesopore volume of MYZ was six times higher than that of YZ. [Fe(terpy)] complexes encapsulated into MYZ and YZ with different Fe contents (Fe(X)L-MYZ and Fe(X)L-YZ; X is the amount of Fe) were prepared and characterized. The oxidation of benzene with HO using Fe(X)L-MYZ and Fe(X)L-YZ catalysts was carried out; phenol was selectively produced with all Fe-containing zeolite catalysts. As a result, the oxidation activity of benzene increased with increasing iron complex content in the Fe(X)L-MYZ and Fe(X)L-YZ catalysts. The oxidation activity of benzene using Fe(X)L-MYZ catalyst was higher than that using Fe(X)L-YZ. Furthermore, adding mesopores increased the catalytic activity of the iron complex as the iron complex content increased.
介孔 Y 型沸石（MYZ）是通过对商业 Y 型沸石（YZ）进行酸碱处理制备的。MYZ 的中孔体积比 YZ 高六倍。将[Fe（terpy）]配合物封装到具有不同铁含量的 MYZ 和 YZ 中（Fe（X）L-MYZ 和 Fe（X）L-YZ；X 是铁的量），并对其进行了表征。使用 Fe（X）L-MYZ 和 Fe（X）L-YZ 催化剂用 HO 氧化苯，所有含铁沸石催化剂都选择性地生成苯酚。结果，随着 Fe（X）L-MYZ 和 Fe（X）L-YZ 催化剂中铁配合物含量的增加，苯的氧化活性增加。使用 Fe（X）L-MYZ 催化剂的苯氧化活性高于使用 Fe（X）L-YZ 的苯氧化活性。此外，随着铁配合物含量的增加，添加中孔增加了铁配合物的催化活性。
