Cubic Pd nanocrystals with shape-controlled mesoporous silica shells have been theoretically designed and successfully synthesized for investigating the effect of a porous nanoshell on catalytic performance of the core. Cubic Pd@cubic mesoporous silica keeps activity of all facets and shows highest catalytic activity and enhanced reusability in the hydrogenation of nitrobenzene.
具有形状可控介孔二氧化硅壳层的立方钯纳米晶体已在理论上设计并成功合成，用于研究多孔纳米壳层对核催化性能的影响。立方钯@立方介孔二氧化硅保留了所有晶面的活性，在硝基苯氢化反应中表现出最高的催化活性和增强的可重复使用性。
