Catalytic nanoclusters of palladium on the surface of polypropylene hollow fiber membranes: removal of dissolved oxygen from water
bookPart
It is widely known that the platinum metal surfaces show good catalytic activity in various reactions. A membrane may be used to facilitate the contact between reactants and catalyst. Gryaznov and his co-workers pioneered the use of palladium membranes in catalytic membrane reactors (CMR), including also many applications of palladium alloy membrane catalysts in liquid-phase hydrogenation. To overcome this problem, catalytic nanoparticles have been immobilized on the surface of porous inorganic or polymeric membranes providing a new type of catalytic membrane reactor, called catalytic diffuser and/or CMR interfacial contactor and/or catalytic contactor. Dissolved oxygen (DO) is one of the major components to be removed for the production of ultra-pure water. Although the concentration of DO in water is very low, approximately 8 ppm at ambient temperature, it causes the oxidation of dissolved components and the materials that it contacts with, for example, the piping of a boiler in the power plant.
