Ionic liquid-Pluronic P123 mixed micelle stabilized water-soluble Ni nanoparticles for catalytic hydrogenation

- The addition of ionic liquid affects the micelle structure of triblock copolymer P123 solutions.
- These mixed micelles can stabilize water-soluble Ni nanoparticles (Ni NPs) effectively.
- The Ni NPs catalyzed selective hydrogenation in aqueous phases.
- The basic IL ([BMMIm]OAc) gave rise to enhanced catalytic activity.
- The Ni NPs were stable enough for eight consecutive catalytic recycles.
