CATALYST FOR EXHAUST-GAS PURIFICATION AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>A catalyst for exhaust-gas purification in which a transition metal is made to retain the effect of improving the activity of noble-metal particles without increasing the production cost or environmental burden. The catalyst for exhaust-gas purification (1) comprises noble-metal particles (2), a first compound (3) which is in contact with the noble-metal particles (2) and inhibits the noble-metal particles (2) from moving, and a second compound (4) in which the noble-metal particles (2) and the first compound (3) are enclosed and which serves to inhibit the noble-metal particles (2) from moving and to inhibit particles of the first compound (3) from coming into contact with one another and aggregating. The first compound (3) supports the noble-metal particles (2). A single particle of or an aggregate of particles of the first compound (3) supporting the noble-metal particles (2) is enclosed in each of sections separated by the second compound (4).</p> |
