Nanoporous PdCo Catalyst for Microfuel Cells: Electrodeposition and Dealloying
SEM images of nanoporous PdCo dendrites: (a–c) plan view, and (d) cross-sectional. The sample shown in “a” and “b” was electrodeposited at a constant current of –50 mA cm−2 for 600 s followed by the immersion in an air-saturated 0.5 M sulfuric acid solution for ~15 h at 60°C. The sample shown in “c” and “d” was prepared by galvanic pulse deposition and dealloying. Reproduced with permission from . Copyright 2010, Elsevier.
