Formation Of Emission Control Catalysts |
| 摘要 |
Provided are processes for the production of particles of catalytic material for emissions control obtainable in one-step from flame spray pyrolysis of precursor-containing dispersion(s), the method comprising: (1) providing a dispersion comprising one or more disperse phases and a continuous phase, the dispersion comprising: (a) a precursor compound of a first platinum group metal and a precursor compound of a first support, and (b) a precursor compound of a second platinum group metal and a precursor compound of a second support, wherein (a) is in a first phase that is different from a second phase containing (b); (2) forming an aerosol of the dispersion provided in step (1); and (3) pyrolyzing the aerosol of step (2) to obtain the particles of catalytic material. The catalytic particles comprise more than one support material and more than one platinum group metal, for use as, for example, three-way conversion (TWC) catalysts. |

1. A process for the production of particles of catalytic material comprising:
(1) providing a dispersion comprising one or more disperse phases and a continuous phase, the dispersion comprising:
(a) a precursor compound of a first platinum group metal (PGM) and a precursor compound of a first support, and(b) a precursor compound of a second platinum group metal (PGM) and a precursor compound of a second support,wherein (a) is in a first phase that is different from a second phase containing (b); (2) forming an aerosol of the dispersion provided in step (1); and (3) pyrolyzing the aerosol of step (2) to obtain the particles of catalytic material. |
