Abstract
The present invention relates to compositions comprising surface modified carbon-clad metal oxide membranes and monoliths. In particular the invention relates to membranes and/or monoliths comprising carbon-clad metal oxide, functionalized with an organic functional group. This organic functional group, either a small molecule or a polymer, can be chosen for specific end-uses, such as selective protein binding, ion exchange, hydrophobic interaction, chiral selection to enhance separations technology.
