NANOSTRUCTURED THIN LAYERS, HAVING HIGH CATALYTIC ACTIVITY, ON THE SURFACES OF NICKEL AND ITS ALLOYS AND METHOD FOR THEIR PRODUCTION

摘要

Thin nanostructured layers on the surfaces of nickel or its alloys for the rapid achievement of high values of hydrogen adsorption (H / Ni ~ 0.7) as a result of providing direct metal / gas contact. Said layers are obtained by a method including the step of oxidizing said surfaces, applying a film of an aqueous silicic acid sol thereon, then heating in an oxidizing atmosphere and final activation as a result of reduction in a reducing atmosphere.
