Active gold and palladium nanoparticles supported on MgO nanocubes and ZnO nanobelts and transition-metal-containing MgO nanobelts were synthesized by combining evaporation and deposition-precipitation techniques. The high activity and stability of the Au/CeO2 and Pd/CeO2 nanoparticle catalysts deposited on the MgO cubes are remarkable and imply that a variety of efficient catalysts can be designed and tested using this approach. The significant increase in the concentration of corner and edge sites in MgO nanocubes make them well-defined supports to study the detailed mechanism of the catalytic activity enhancement.
通过结合蒸发和沉积沉淀技术，合成了负载在氧化镁纳米立方体、氧化锌纳米带以及含过渡金属的氧化镁纳米带上的活性金和钯纳米颗粒。负载在氧化镁立方体上的金/二氧化铈和钯/二氧化铈纳米颗粒催化剂具有很高的活性和稳定性，这意味着可以使用这种方法设计和测试各种高效催化剂。氧化镁纳米立方体中角位和边位浓度的显著增加，使其成为研究催化活性增强详细机制的明确载体。
