Stabilizing structure of tertiary amine-protected rhodium colloid dispersions in chloroform

摘要: Tertiary amine-protected rhodium colloids have been prepared in chloroform by phase transfer of a rhodium(III) salt from an aqueous to the organic followed reduction with hydrogen. The colloid dispersions, thus prepared, present narrow size distribution and are stable. structure protecting amine molecules on surface was investigated NMR spectroscopy, transmission electron microscopy (TEM), hydrodynamic radius measurements according Taylor dispersion method. Carbon-13 spectroscopy can provide some information conformation surface. entire including layer surrounding metal surface, obtained method, is considered be fairly consistent naked particles TEM adsorbed layer, supports conformational information.
