PLATINKATALYSATOR UND VERFAHREN FUER SEINE HERSTELLUNG.

摘要

Disclosed herein are a platinum catalyst and a process for preparing the same. The catalyst comprises carbon supports and the carbides of (i) platinum and of (ii) one or more metals selected from the group consisting of nickel, cobalt, chromium and iron, and if necessary of (iii) manganese, supported on the carbon supports. The catalyst possesses superior catalyst performance because the catalyst metals are firmly fixed to the carbon supports by mean of the carburizing. The process for preparing the platinum catalyst includes alloying the metals by employing their organic acid amine salts. This alloying requires a lower temperature than that in a conventional process so that the movement of the metals which leads to agglomeration thereof can be advantageously prevented.
