By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Solvents are presented in a new report. According to news reporting out of Kanagawa, Japan, by NewsRx editors, research stated, "The electroless deposition of Pt nanoparticles (Pt-NPs) could be carried out by dissolving potassium tetrachloroplatinate(II) (K-2[PtCl4]) in 1-ethyl-3-methylimidazolium (EMI+) room-temperature ionic liquids (RTILs) containing bis(trifluoromethylsulfonyl) imide (NTf2-) or tetrafluoroborate (BF4-) anion and small cations, such as H+, K+ and Li+. In this case, no deposition of Pt-NPs occurred in RTILs without such small cations."
Our news journalists obtained a quote from the research from the Tokyo Institute of Technology, "The formation of Pt-NPs was only observed in RTILs containing trifluoromethanesulfonimide (HNTf2) and protons at high temperature (>= 80 degrees C C) when potassium hexachloroplatinate(IV) (K-2[PtCl6]) was dissolved in the RTILs. The characteristic absorption spectrum of ultrasmall Pt-NPs. The ultrasmall and uniform Pt-NPs of ca. 1-4 nm in diameter were produced and the Pt-NPs/ EMI+NTf2- dispersion was kept stably for several months without adding any additional stabilizers or capping molecules. The identified Fourier-transform patterns along the [0 1 1] zone axis were observed for the TEM images of Pt-NPs."
According to the news editors, the research concluded: "On the basis of the results obtained, a probable mechanism of the electroless formation of Pt-NPs is discussed."
