| 发明名称 | Supported noble metal catalyst | ||
| 摘要 | A supported noble metal catalyst comprising palladium salts enveloped by colloids applied to the support is produced by hydrolysing a palladium salt solution by means of a base and applying the colloidal suspension to a support. The catalyst can be used in hydrogenations. | ||

| 主权项 | 1. A supported noble metal catalyst, comprising a palladium salt and colloids of palladium hydroxide/oxide and/or palladium hydroxide/oxide compounds that envelop said palladium salt and wherein said palladium salt and said colloids are on a support, wherein: a) prior to the use of said supported noble metal catalyst to catalyze a reaction, the palladium on said supported noble metal catalyst is in the form of unreduced palladium (II); and b) said catalyst has a pH of less than 3 after reduction by hydrogen. | ||
