用一维CeO2纳米管替代非一维结构的商用CeO2,用于负载Pd而制得的催化剂在空气气氛下高温煅烧过程中Pd纳米粒子的团聚受到明显抑制,在选择性有氧氧化苯甲醇生成苯甲醛反应中,所制CeO2纳米管负载的Pd催化剂表现出更高的催化活性.可见,一维金属氧化物材料有望用作载体以抑制贵金属纳米粒子的团聚,从而提高其催化性能. One-dimensional CeO2 nanotubes instead of non-one-dimensional structure of commercial CeO2, Pd catalyst for the preparation of high temperature calcination in air atmosphere during the process of Pd nanoparticles were significantly inhibited, in the selective aerobic oxidation of benzyl alcohol production In the benzaldehyde reaction, the Pd catalyst prepared by CeO2 nanotubes showed higher catalytic activity, and it can be seen that the one-dimensional metal oxide material is expected to be used as a carrier to inhibit the agglomeration of noble metal nanoparticles to improve their catalytic performance.
