Rossi definitely did not use Raney Nickel. He has said so several times, and there is independent confirmation.
Rossi's patent: https://www.ecat.tech/sites/de…276050651-25-aug-2015.pdf says: group 10 element, for example nickel. And also goes on to say: porosity-enhanced nickel powder plus lithium powder plus lithium aluminium hydride powder.
However, there may perhaps also be some Oxygen, Oxide, H2O (or similar species) in there to help dissociate Hydrogen into H+ and H2O.H- Who knows?
