Abstract:
The present invention relates to a process for forming cobalt nanoparticles and coating them with copper or copper oxide, in which process a copper salt is mixed to a cobalt salt so that the formed salt mixture obtains a cobalt:copper ratio of >1:1, and a reduction is carried out with a reducing gas, whereby nanoparticles are formed while a coating is formed onto their surface.
