Facile Aqueous‐Phase Synthesis of Uniform Palladium Nanoparticles of Various Shapes and Sizes

Uniform palladium nanoparticles of various sizes and shapes are synthesized via a simple aqueous-phase reaction between Pd2+ ions and PEOx–PPOy–PEOx triblock copolymers; the size and shape are controlled by varying reaction conditions such as the pH value (see image). The palladium nanoparticles showed high catalytic activities for Suzuki cross-coupling reactions.
