Claim 15:
16. A method of preparing a catalytic assembly, comprising:
inserting a hollow fiber membrane into a first solution comprising alginate, wherein the hollow fiber member comprises an inner surface defining a channel and an outer surface;
removing the hollow fiber membrane from the first solution, wherein the outer surface of the hollow fiber membrane is at least partially coated with an alginate solution coating;
inserting the hollow fiber membrane with the alginate solution coating into a second solution comprising Ca2+ and Pd2+, whereupon the Ca2+ reacts with the alginate in the alginate solution coating to form a hydrogel coating on the outer surface of the hollow fiber membrane, wherein the hydrogel coating comprises Ca-crosslinked alginate, and wherein Pd2+ ions are dispersed throughout the hydrogel coating; and
removing the hollow fiber membrane with the hydrogel coating from the second solution and inserting the hollow fiber membrane with the hydrogel coating into a third solution comprising NaBH4, whereupon the NaBH4 reduces the Pd2+ ions dispersed throughout the hydrogel coating to form Pd nanoparticles embedded in the hydrogel coating.
