Uniform palladium nanoparticles of various sizes and shapes are synthesized via a simple aqueous‐phase reaction between Pd 2+ ions and PEO x –PPO y –PEO x 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.
