Hydrogen is one of the most efficient embrittling atomic species introducing both structural and chemical changes in solid materials and eventually, causing their degradation. This highly detrimental effect - when controlled - may, however, be used in benefit of e.g. enhancing catalytic activity of materials by increasing their specific surface area and modifying surface chemistry. This method was used to activate Cu-Hf (Cu65Hf35, Cu61Hf39) amorphous alloys for catalytic purposes.
