摘要:

选择高比表面积以及高孔隙率的UiO?66为载体,通过浸渍法添加Cu(NO3)2制备了复合催化剂UiO?66/Cu。采用X射线衍射(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)等手段对所制备的催化剂进行表征,考察了催化剂在不同负载量、质量浓度条件下的催化效果。结果表明,当对硝基苯酚浓度为5×10-5 mol/L、UiO?66/Cu?10质量浓度为10 mg/L时,催化效果最佳,5 min内对对硝基苯酚的催化还原转化率达到97.0%以上。

Abstract:

UiO?66 has the high specific surface area and porosity, which was selected as a carrier in this study. The impregnation method by loading nano?metal Cu particles was used to prepare the composite catalyst UiO?66/Cu. X?ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and other methods were carried out to characterize the prepared catalysts. Different loads and dosages catalytic effects in catalytic reduction were investigated in this study. The concentration of p?nitrophenol was 5×10-5 mol/L and the dosage of UiO?66/Cu?10 was 10 mg/L, which were the optimal solutions for catalytic effect. Catalytic reduction efficiency of p?nitrophenol could reach more than 97.0% in 5 minutes.

Key words: UiO?66, Nano Cu particles, p?nitrophenol, catalysis
