摘要

采用一锅法制备了氨基功能化的SBA-15硅载体（PMO-pr-NH2），然后通过吸附结合原位制备技术合成了HKUST-1功能复合材料（HKUST-1@PMO-pr-NH2）。采用一系列表征技术对复合材料进行了分析，如 BET、傅立叶变换红外光谱、TEM、XPS、TG、SEM 和 XRD。分析表明，在 PMO-pr-NH2 硅基载体的孔隙中成功制备了 HKUST-1。利用 4-硝基苯酚（4-NP）转化为 4-氨基苯酚（4-AP）的反应研究了该复合材料的催化还原活性和热稳定性。经过 4 次循环后，复合材料的催化性能没有发生明显变化。

Metal–organic frameworks HKUST-1 embedded in amino-functionalized SBA-15: Efficient catalytic reduction of 4-nitrophenol to 4-aminophenol

The amino-functionalized SBA-15 silicon carrier (PMO-pr-NH₂) was prepared by the one-pot method, and then HKUST-1 functional composites were synthesized by adsorption combined with in-situ preparation technology (HKUST-1@PMO-pr-NH₂). A series of characterization techniques were used to analyze composites, such as BET, FTIR, TEM, XPS, TG, SEM, and XRD. The analysis showed that HKUST-1 was successfully prepared in the pores of the PMO-pr-NH₂ silicon-based carrier. The catalytic reduction activity and thermal stability of the composite material were investigated using the reaction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP). After 4 cycles, the catalytic performance of the composites was maintained without any obvious change.
