Electrochemical recycling of homogeneous catalysts

Science Advances, 2022
Homogeneous catalysts have rapid kinetics and keen reaction selectivity. However, their widespread use for industrial catalysis has remained limited because of challenges in reusability. Here, we propose a redox-mediated electrochemical approach for catalyst recycling using metallopolymer-functionalized electrodes for binding and release ...

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 ...
