摘要
(Figure Presented) A remedy for etching: Citric acid and citrate ion were used to prevent oxidative etching from the reaction system by taking advantage of their strong binding to Pd surfaces. This method allowed Pd icosahedra (see picture) to be formed in yields as high as 80%. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
