Researchers have developed a new method of using rare and expensive catalysts as sparingly as possible. They enclosed a precious metal salt in outer shells, tiny micelles, and had them strike against a carbon electrode, thus coating the surface with nanoparticles of the precious metal contained in the micelles.
