<p><P>PROBLEM TO BE SOLVED: To provide a metal catalyst which can exert a catalyst activity even at 400°C or less though the activity of the conventional alloy-based catalysts can be expected only at high temperatures of at least 450°C and the use in a very limited environment is required. <P>SOLUTION: The catalyst is an ordered intermetallic compound having a chemical composition represented by the chemical formula 1: A<SB>x</SB>T<SB>y</SB>(1) (A: Rh, Ir, Pd, or Pt; T: Ti, Zr, Hf, V, Nb, or Ta). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
