Three groups of catalysts clearly show affinities toward : ( 1 ) hydrogen formation [ on early transition metals ( Ti , V , Cr , Mn , Zr , Nb , Mo , Hf , Ta , We , and Re ) and platinum group metals ( Ru , Rh , Ir , and Pt ) ] , ( 2 ) sorbitol formation [ on late transition metals ( Fe , Co , Ni , Cu , Pd , Au , and Ag ) and Al ( sp metal ) ] , and ( 3 ) sorbitol and 2 - deoxysorbitol formation [ on post - transition metals ( In , Sn , Sb , Pb , and Bi ) , as well as Zn and Cd ( d metals ) ] .
