Firing (calcination) process and method related to metallic substrates coated with ZPGM catalyst |
摘要 |
The effect of firing (calcination) cycle on metallic substrates in ZPGM catalyst systems is disclosed. ZPGM catalyst samples with washcoat and overcoat are separately fired in a normal, slow and fast firing cycles to determine the optimal firing cycling that may provide an enhanced catalyst performance, as well as the minimal loss of washcoat adhesion from the samples. |

1. A method of controlling a firing cycle for use with catalytics, comprising:
providing at least one substrate; depositing a washcoat suitable for deposition on the substrate, the washcoat comprising at least one oxide solid further comprising at least one carrier metal oxide; calcinating the washcoat through at least one first heating and at least one second heating; depositing an overcoat suitable for deposition on the substrate, the overcoat comprising at least one oxygen storage material and at least one ZPGM catalyst; wherein the at least one ZPGM catalyst comprises at least one compound having the formula AB2O4, wherein each of A and B is selected from the group consisting of at least one of copper and cerium; and wherein one of the at least one carrier metal oxide is a mixed metal oxide. |
