Hierarchically porous MIL-101(Cr) (H-MIL-101(Cr)) with meso/macro-pores was directly prepared via nanofusion progress by using butyric acid as a modulating agent. In the methyl orange (MO) adsorption experiments, H-MIL-101(Cr) showed a high adsorption capability of 369.8 mg g, which was 1.52-fold greater than that of pristine MIL-101(Cr) (P-MIL-101(Cr)). While in the oxidation reaction of indene and 1-dodecene tests, H-MIL-101(Cr) presented much higher catalytic efficiency, with turnover frequency (TOF) values of 0.7242 mmol g min and 0.1492 mmol g min, respectively, which were 28% and 34% greater than that in the case of P-MIL-101(Cr). Thus, compared with P-MIL-101(Cr), H-MIL-101(Cr) exhibited better removal efficiency and higher levels of activity in the oxidation reactions of indene and 1-dodecene. The unique structure of H-MIL-101(Cr) also contributed to its superior performance in these processes.
通过以丁酸作为调节剂，经由纳米融合过程直接制备出具有介孔/大孔的分级多孔MIL-101（Cr）（H-MIL-101（Cr））。在甲基橙（MO）吸附实验中，H-MIL-101（Cr）展现出369.8 mg/g的高吸附能力，这比原始MIL-101（Cr）（P-MIL-101（Cr））的吸附能力高1.52倍。而在茚和1-十二碳烯的氧化反应测试中，H-MIL-101（Cr）表现出更高的催化效率，其周转频率（TOF）值分别为0.7242 mmol g⁻¹ min⁻¹和0.1492 mmol g⁻¹ min⁻¹，分别比P-MIL-101（Cr）的情况高28%和34%。因此，与P-MIL-101（Cr）相比，H-MIL-101（Cr）在茚和1-十二碳烯的氧化反应中表现出更好的去除效率和更高的活性水平。H-MIL-101（Cr）的独特结构也促成了其在这些过程中的卓越性能。
