  Ionization potentials and reactivity of coinage metal clusters

  摘要：

  The ionization potentials of several homoatomic and heteroatomic coinage metal clusters have been determined utilizing charge-transfer bracketing and Fourier transform ion cyclotron resonance (FTICR) mass spectrometry. The clusters studied were Ag(n), Au(n), Cu(m), and Ag(k)Cu(l), where n = 2,3,5, m = 2,3, and k and l = 1,2. Atomic ionization potentials were also verified for each of the above metals as a test of the bracketing method. This work represents one of the first measurements of adiabatic ionization potentials for any of the above clusters. A number of additional reactions were observed between several of the charge-transfer agents and metal cluster ions, including some which resulted in metal-metal bond cleavage.

  Absorption Spectrum and Some Chemical Reactions of Colloidal Platinum in Aqueous Solution

  摘要：

  The radiolytic reduction of PtCl42- in the presence of 10(-3) M sodium polyphosphate (2 x 10(-4) to 5 x 10(-3) M) and 10(-2) M methanol yields colloidal Pt particles of irregular shape, 10-30 Angstrom in diameter (''radiolysis'' colloid). The reduction of PtCl42- is partly autocatalytic. The reduction of the aquated complexes, (PtCl2(H2O)(2) and PtCl3(H2O)(-), by hydrogen in the presence of 5 x 10(-4) M sodium polyacrylate or polyphosphate leads to colloidal particles of regular shape, 50-80 Angstrom in diameter (''hydrogen'' colloid). The absorption spectrum of the ''radiolysis'' and ''hydrogen'' colloids is compared to the previously reported spectra of colloids which were prepared using citrate or poly(vinyl alcohol) as stabilizer. The spectra of the presently prepared colloids have the predicted absorption maximum at 215 nm. The Pt particles tend to form clusters, whose absorption spectrum is rather flat with a maximum at 260 nm. A few reactions of the new colloids are described and their reactivities compared to that of a colloid prepared by citrate reduction of PtCl62-. Significant differences in the reactivity toward O-2, H-2, and Au(CN)(2)(-) exist between the various colloids as well as in their ability to catalyze the autoxidation of propanol-2. The differences are discussed in terms of differences in particle size and in the oxidation state of the particle surface.
