carbono catalisador/carbono como base para a catálise
Creio sesre isto. Espere que ajdue.
blacks deve estar se referindo ao elemnto químico "carbono".
- In particular, platinum-ruthenium binary alloys are largely preferred in terms of catalytic activity, and they have been used both as catalyst blacks and as supported catalyst, for example on active carbon, and in most of the cases incorporated into gas diffusion electrode structures suited to be coupled to ion-exchange membranes.
Platinum and ruthenium are, however, very difficult to combine into true alloys: the typical Pt: Ru 1: 1 combination disclosed in the prior art almost invariably results in a partially alloyed mixture. The method for the production of binary combinations of platinum and ruthenium of the prior art starts typically from the co-deposition of colloidal particles of suitable compounds of the two metals on a carbon support, followed by chemical reduction.
