摘要：

High surface area Pd foams with roughness factors of more than 1000 and a specific surface area of 60 m(2) g(-1) are obtained by electrodeposition. The foams are composed of dendrites with branches on the 10 nm scale. The resulting electrodes show high activity towards the oxidation of C(2) alcohols.
