摘要： The invention provides a noble metal-containing supported catalyst which contains one of the noble metals from the group Au, Ag, Pt, Pd, Rh, Ru, Ir, Os or alloys of one or more of these noble metals in the form of noble metal particles on a powdered support material. The particles deposited on the support material have a degree of crystallinity, determined by X-ray diffraction, of more than 2 and an average particle size between 2 and 10 nm. The high crystallinity and the small particle size of the noble metal particles lead to high catalytic activity for the catalyst. It is particularly suitable for use in fuel cells and for the treatment of exhaust gases from internal combustion engines.

摘要： The invention provides a process for preparing a platinum-ruthenium catalyst and the catalyst prepared therewith. The catalyst can be supported on a support material in powder form or may also be unsupported. To prepare the supported catalyst, the support material is suspended in water and the suspension is heated to at most the boiling point. While keeping the temperature of the suspension the same, solutions of hexachloroplatinic acid and ruthenium chloride are then added to the suspension, then the pH of the suspension is increased to a value between 6.5 and 10 by adding an alkaline solution and the noble metals are thus precipitated onto the support material. Afterwards, one or more organic carboxylic acids and/or their salts are added to the suspension and the catalyst is chemically reduced, washed, dried and optionally subsequently calcined under an inert or reducing atmosphere at a temperature between 300 und 1000° C. The catalyst is characterised by a high tolerance to carbon monoxide poisoning in the fuel cell.
摘要翻译：本发明提供了制备铂 - 钌催化剂的方法及其制备的催化剂。催化剂可以以粉末形式负载在支撑材料上，或者也可以是不支撑的。为了制备负载的催化剂，将载体材料悬浮在水中，并将悬浮液加热到至多沸点。在保持悬浮液的温度相同的同时，向悬浮液中加入六氯铂酸和氯化钌溶液，然后通过加入碱性溶液将悬浮液的pH增加至6.5至10之间，因此贵金属沉淀在支撑材料上。之后，将一种或多种有机羧酸和/或其盐加入到悬浮液中，催化剂被化学还原，洗涤，干燥，任选地在惰性或还原气氛下在300-1000℃的温度下煅烧。催化剂其特征在于对燃料电池中一氧化碳中毒的高耐受性。
