Abstract

Procedimiento para preparar un catalizador a base de metal precioso, un material de vehículo y eventualmente de aditivos usuales, y que comprende: a) una zona tridimensional de borde pobre en o exenta de metal precioso, b) una zona tridimensional anular rica en metal precioso, c) un núcleo pobre en o exento de metal preciso; caracterizado porque a) se impregna el material de vehículo con una solución de por lo menos una sal de metal precioso, de tal modo que el material de vehículo absorbe la solución, b) se seca el vehículo y la solución absorbida, c) se agrega al vehículo secado una solución alcalina en tal cantidad que esta es absorbida, siendo las sales de metal precioso transformadas en compuestos insolubles y mostrando un extracto acuoso posteriormente obtenido un valor pH mayor de 7, y d) se trata el vehículo con un agente de reducción para transformar los compuestos insolubles de metal preciosos en el correspondiente metal precioso.
