The colloidal dispersions are prepared by reducing suitable precious metal precursor compounds in aqueous alkaline solutions at reaction temperatures between 40 and 70°C and a pH = 12.0 in the presence of polysaccharides with average molecular weights (M w) in the range of 300.000 to 1.000.000. The precious metal nanoparticles are isolated after decomposing the polysaccharide by heating the colloidal dispersions to temperatures > 80°C. The nanoparticles can be used for the manufacture of core/shell-type catalyst materials and for electronic, decorative and medical applications.

摘要： The present invention provides a method for manufacture of supported noble metal based alloy catalysts with a high degree of alloying and a small crystallite size. The method is based on the use of polyol solvents as reaction medium and comprises of a two-step reduction process in the presence of a support material. In the first step, the first metal (M1 = transition metal; e.g. Co, Cr, Ru) is activated by increasing the reaction temperature to 80 to 160 °C. In the second step, the second metal (M2 = noble metal; e.g. Pt, Pd, Au and mixtures thereof) is added and the slurry is heated to the boiling point of the polyol solvent in a range of 160 to 300 °C. Due to this two-step method, an uniform reduction occurs, resulting in noble metal based catalysts with a high degree of alloying and a small crystallite size of less than 3 nm. Due to the high degree of alloying, the lattice constants are lowered. The catalysts manufactured according to the method are used as electrocatalysts for polymer electrolyte membrane fuel cells (PEMFC), direct-methanol fuel cells (DMFC) or as gas phase catalysts for CO oxidation or exhaust gas purification.
摘要翻译：本发明提供一种具有高合金化和微晶尺寸的负载型贵金属基合金催化剂的制造方法。该方法基于使用多元醇溶剂作为反应介质，并且包括在存在载体材料的情况下的两步还原方法。在第一步骤中，第一金属（M1 =过渡金属，例如Co，Cr，Ru）通过将反应温度升高至80至160℃来活化。在第二步骤中，加入第二金属（M2 =贵金属，例如Pt，Pd，Au及其混合物），并将浆料加热到多元醇溶剂的沸点在160-300℃的范围内。由于这种两步法，发生均匀的还原，导致具有高合金化度和小于3nm的微晶尺寸的贵金属基催化剂。由于高合金化，晶格常数降低。根据该方法制造的催化剂用作聚合物电解质膜燃料电池（PEMFC），直接甲醇燃料电池（DMFC）或用于CO氧化或废气净化的气相催化剂的电极催化剂。
