| 摘 要： | 采用溶胶凝胶法和浸渍法,在500℃下焙烧2 h,制备不同组成的B2O3／Al2O3催化剂。通过X射线衍射、热失重、傅立叶红外光谱等测试方法对所制备的催化剂的结构进行表征。通过催化剂与二苯甲酰基甲烷(DBM)配位情况对催化剂的性能表征。研究表明:焙烧获得的主催化剂晶型为γ-Al2O3,添加第二组分B2O3,可以提高与DBM的配位能力,以改善Al2O3的催化活性。

| Abstract: | B2O3/Al2O3 mixed oxides with various B2O3 contents were synthesized by sol-gel method and impregnation methods, then calcinated at 500℃in 2 hours. The mixed oxides were characterized by X-ray diffraction, Thermo-gravimetry and Fourier infrared spectroscopy. Catalyst were complexed with dibenzoylmethane (DBM) to study catalytic activity. The results obtained indicate aluminum oxide wasγ-Al2O3 after calcination. Addition of boron which used as the second part could increase the catalytic activity. |
