Summary:
Polymer based membranes will be combined with catalysis in several ways. In a first instance, homogeneous catalysts will be immobilized in the membrane matrix to get heterogenised this way, but also to have simultaneous improved mass transfer. For the latter reasons, also heterogeneous catalysts will be incorporated.
Alternatively, homogeneous catalysts will be recycled and used in continuous operations, by combining them with dialysis membranes or solvent resistant nanofiltration (SRNF). SRNF is a relatively new membrane process with a wide variety of applications, among others in catalysis. Indeed, SRNF-membranes allow separations on a molecular level, thus offering possibilities to retain the catalyst while allowing product permeation or viceversa. In addition, it also allows fundamental study of the reaction mechanism of homogeneous catalysis.
