A one-step, reproducible and controllable method to directly grow nanoporous platinum-ruthenium networks is demonstrated. The synthesized nanoporous PtRu networks not only possess a huge active surface area, but also exhibit superior activity towards the electrochemical oxidation of CO and methanol compared to a bare Pt surface.
