“…[4][5][6][7][8][9][10][11] Very recently, we have reported the unique catalytic performance for hydrogen-induced amorphization (HIA) of CeNi 2 under CO hydrogenation, highlighting that HIA has a potential of new preparation method and activation treatment for IMCs used as catalysts. 12,13) HIA is very interesting phenomenon because of the reverse transformation from the crystalline state into the amorphous one by hydrogen absorption. 14) Moreover, there is a wide variety of HIA conditions according to the alloy systems from low pressure and/or temperature to high pressure and/or temperature, 15) allowing to choice any IMCs suitable for a specific catalytic reaction.…”
