Capping agent exchange with PVP The obtained Co2P nanoparticles were dissolved in 10 mL n-hexane and added to a solution containing 200 mL trichloromethane and 2.0 g PVP. The reaction was then heated to 65 ¡æ and refluxed for 12 h under an Ar atmosphere. After the mixture was cooled to room temperature, acetone was added to cause flocculation and the mixture was centrifuged to separate the black precipitate. The obtained black solid was washed with acetone three times and dried in a vacuum oven. The final product could readily dissolve in water.
