A gentle, seedless, and surfactant-free method for the preparation of clean-surface, porous, platinum nanoparticles is described. The as-synthesized nanoparticles show higher activity than a commercial Pt/C catalyst for electrocatalytic methanol oxidation. In addition, an electrochemical method and DFT calculations were utilized to study the inhibition effects of surfactants on the catalytic activity. For more details, see the Full Paper by B. Geng et al. on page 240 ff.
