The Fast Formation of a Highly Active Homogeneous Catalytic System upon the Soft Leaching of Pd Species from a Heterogeneous Pd/C Precursor

Inorganics, 2023
Understanding the interface between soluble metal complexes and supported metal particles is important in order to reveal reaction mechanisms in a new generation of highly active homogeneous transition metal catalysts. In this study, we show that, in the

Recyclable nanosize homogeneous catalysts [PDF]

Comptes Rendus. Chimie, 2003
For industrial chemical processes, it would be highly desirable from both a commercial and an environmental point of view to incorporate the advantages of homogeneous and heterogeneous catalysis into one chemical process. The ultimate goal is to design a catalytic system with the high activity and selectivity of homogeneous catalysts, the efficient ...
