Catalyst material, based on a titanium-copper alloy and process for producing the same.

摘要

A Ti-Cu based alloy catalyst material having a composition including at least one element selected from the group consisting of V, Ni, Zr, Cr, Mn, Fe and Co as a partial substitute element for Ti and/or Cu in a composition represented by the general formula Ti100-aCua, wherein "a" is, in atomic %, 30 </= a </= 50, 0.1 to 20 atomic % in the general formula Ti100-aCua being substituted with said at least one element, in which a fine Ti-Cu intermetallic compound having a mean particle size of 10 nm or less is uniformly precipitated in an amorphous phase and/or alpha -Ti matrix. The alloy catalyst is produced by preparing an alloy of the above-specified composition having an amorphous phase and/or alpha -Ti matrix, and heating the alloy at a temperature of from the transformation temperature Tx of a non-equilibrium phase minus 50 K to the transformation temperature Tx plus 100 K so as to precipitate a fine Ti-Cu intermetallic compound in the matrix. The catalyst material is not only excellent in mechanical properties but also useful as a catalyst for various reactions.
