Abstract

Expanding the catalytic environment to a nanosize must be one of the most promising ways to improve the performance of homogeneous catalysts. In this Forum Article, recent developments in homogeneous nanosize palladium catalysts are reviewed. It contains solubilized palladium nanoparticles, metalated dendrimers, and complexes with well-defined nanosized ligands. These systems realize efficient catalyst recycling, unique selectivity, suppression of metal aggregation, and remarkable enhancement of the catalytic activity.

摘要

将催化环境扩展到纳米尺寸必定是提高均相催化剂性能最具前景的方法之一。在这篇论坛文章中，综述了均相纳米钯催化剂的最新进展。它包括溶解的钯纳米颗粒、金属化树枝状大分子以及带有明确纳米尺寸配体的配合物。这些体系实现了高效的催化剂循环利用、独特的选择性、抑制金属聚集以及催化活性的显著增强。
