| 摘 要： | 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. |

| Abstract: | One-dimensional (1D) CeO2 nanotubes can be used as a support to inhibit Pd nanoparticle aggregation during the high temperature calcination process in air. This is in opposition to the significant aggregation of Pd particles that is observed for the preparation of supported Pd metal catalysts using non-1D commercial CeO2 as support. The as-prepared Pd/CeO2 nanotube catalyst exhibits much higher catalytic performance than Pd/commercial CeO2 toward the aerobic selective oxidation of benzyl alcohol to benzaldehyde. This work suggests that 1D metal oxide materials can be used as a promising class of supports to inhibit noble metal nanoparticle aggregation, thereby improving catalytic performance toward target reactions. |
