Õâ¶Î»°Õª×ÔJACS The platinum nanoparticles(Pt NPs)were prepared according to the procedure reported elsewhere. 2.6 mg of H2PtCl6(0.56 mM)was added to 9 mL of an aqueous solution containing 50 mM sodium citrate(0.67 mM),then under vigorous stirring,1 mL of aqueous sodium borohydride(NaBH4)solution(30 mM)was added dropwise.The solution was kept stirring for another half hour.The particle sizes ranged between 2 and 6 nm distributed mainly at 4¡À0.8 nm in diameter.Assuming a particle contains about 2000 Pt atoms2,the stock solution was about 0.3¦ÌM in particles.

Usually this means the final molar concentration of the chemicals in the mixture solution, but the calculation seems not so accurate ´when considering the final solution volume of 10 ml. Maybe you can check the original paper that the authors referred to. Good luck! |
