Electroless Metal Deposition Using Anodic Alumina as a Template

2 Electroless Metal Deposition Using Anodic Alumina as a Template 

The resulting metal membrane has a structure similar to the bulk pores of the anodic alumina but without the dense skin layer and has straight through-pores. Nickel and platinum membranes having pore diameters in the 15 to 200 nm range can be produced this way. One of the critical steps of this method is depositing palladium catalyst on the surface, but not inside the pores, of the anodic alumina. The catalyst is used to facilitate the deposition of metal from the bottom to the surface of the cylindrical pores.
