    The Preparation Methods of Pt/SnO2 Catalyst Dope by REOX

      摘要
    • 摘要: 以共沉淀法制备的氧化锡和氧化铈混合物为载体,负载Pt,得到含稀土氧化物的Pt/SnO2催化剂.考察了该催化剂对CO氧化的催化活性,并与以氧化锡为载体、用浸渍法制备得含稀土氧化物的Pt/SnO2催化剂进行了比较.实验结果表明:两者对于CO的催化氧化活性基本相同.还进一步考察了该催化剂中晶格氧的作用.

       

      Abstract: Pt/SnO2 catalyst doped by rare earth oxide (REOX) was prepared by impregnating Pt on the carrier of stannous dioxide and cerium oxide obtained by co-preparation. The catalytic activity for CO oxidation was reseached, and compared with that prepared by impregnating cerium oxide on Pt/SnO2. The results show that the catalytic activity of Pt/SnO2 doped cerium oxide gained by different methods were the same basically. The action of lattice oxygen in the catalysts was also observed.
