Recyclable nanosize homogeneous catalysts

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 catalyst recycling of heterogeneous catalysts and which has a high (thermal) stability for extended use. Ultimately, this leads to cleaner, faster and cheaper catalytic processes and eventually will lead to green commercial processes. (C) 2003 Academie des sciences.
