The use of ultra- and nanofiltration techniques in homogeneous catalyst recycling.

In recent years, the application of membrane technology in homogeneous catalyst recycling has received widespread attention. This technology offers a solution for the major drawback of homogeneous catalysis, that is, recycling of the catalyst. From both an environmental and an industrial point of view, this technology is very interesting, since it allows the future application of homogeneous catalysts in the synthesis of commercial products, leading to faster, cleaner and highly selective green industrial processes. In this account, an overview is given of the promising results obtained in the field of homogeneous catalyst recycling using nanofiltration membrane technology.
