| 摘 要： | 以多孔金属有机骨架UIO-66为基材，采用浸渍还原法分别合成了Au@UIO-66和Pd@UIO-66两种负载型催化剂，通过透射电镜（TEM）、X射线衍射（XRD）、红外光谱（IR）、N2物理吸脱附对所制备催化剂进行了表征。结果表明：尺寸为13 nm的金纳米粒子（AuNPs）均匀分散在载体上，钯纳米（PdNPs）呈现出纳米粒子（粒径5~8 nm）和纳米线两种状态，且分散均匀。研究了两种催化剂在不同条件下催化还原对硝基苯酚的性能，结果表明：Au@UIO-66和Pd@UIO-66这两种催化剂都具有较高的催化活性，各使用10 mg催化100 mL、1.6×10-4 mol/L的对硝基苯酚溶液，5 min内对硝基苯酚都可达到95%以上的转化率。

| Abstract: | Using metal-organic framework (UIO-66) as the support,two supported catalysts Au@UIO-66 and Pd@UIO-66 were prepared by impregnation reduction method and characterized by transmission electron microscope (TEM),X-ray diffraction (XRD),infrared spectroscopy (IR) and N2 adsorption-desorption.The results showed that gold nanoparticles with size of 13 nm were uniformly dispersed on the carrier and the nano-palladiums also dispersed uniformly on UIO-66 as 5-8 nm nanoparticles and nanowires.The catalytic performance of two catalysts in the catalytic reduction of p-nitrophenol under different conditions was studied.Both catalysts had high catalytic activity.When 10 mg catalyst was used in 100 mL p-nitrophenol aqueous solution (1.6×10-4 mol/L),the conversion of p-nitrophenol can reach more than 95% within 5 min. |
