|
請問各位蟲蟲: 氯鉑酸H2PtCl6·H2O,可以溶于乙二醇(EG)嗎?溶解度如何?此外,乙醇可以還原氯鉑酸,乙二醇可以嗎?乙醇還原氯鉑酸的機(jī)理是什么?望各位不吝賜教,小蟲將不勝感激。! |

kyi 可以 。請參考 等等,我去給你找。 Wang, Y., et al. (2000). "Preparation of Tractable Platinum, Rhodium, and Ruthenium Nanoclusters with Small Particle Size in Organic Media." Chemistry of Materials 12(6): 1622-1627. ---------------------------------------------------------------------------------------------- Preparation of “Unprotected” Platinum Nanoclusters. All operations were carried out under inert atmosphere (Ar or N2). In a typical preparation, a glycol solution of NaOH (50 mL, 0.5 M) was added into a glycol solution of H2PtCl6a6H2O (1.0 g, 1.93 mmol in 50 mL) with stirring to obtain a transparent yellow platinum hydroxide or oxide colloidal solution which was then heated at 160 °C for 3 h, with an Ar flow passing through the reaction system to take away water and organic byproducts. A transparent dark-brown homogeneous colloidal solution of the Pt metal nanocluster (Pt: 3.76 g/L glycol, 19.3 mmol/L) was obtained without any precipitate. The obtained Pt nanocluster solution is very stable, no precipitate was observed after standing for several months. 北京大學(xué) 王遠(yuǎn) http://www.chem.pku.edu.cn/wangy/index2/wangy.htm [ Last edited by linqi723 on 2013-5-21 at 16:30 ] |
