An introduction to the concept of a ‘cocktail’ of catalysts is provided together with a brief description of experimental methods and approaches to study ‘cocktail’-type catalytic systems. The evolution of catalytically active centers and dynamic phenomena in heterogeneous and homogeneous catalysis are summarized. The key role of processes such as leaching, ligand transformations, aggregation and redeposition is highlighted. Two principal pathways to afford ‘cocktail’-type catalytic systems (bottom-up and top-down) are discussed in view of the participation of metal complexes, clusters, and nanoparticles in catalysis.

过渡金属“鸡尾酒”型催化

介绍了催化剂“鸡尾酒”的概念，并简要介绍了研究“鸡尾酒”型催化体系的实验方法和方法。总结了催化活性中心的演化以及非均相和均相催化的动力学现象。突出了诸如浸出，配体转化，聚集和再沉积等过程的关键作用。鉴于金属络合物，簇和纳米颗粒参与催化作用，讨论了提供“鸡尾酒”型催化系统的两​​种主要途径（自下而上和自上而下）。
