Abstract
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.
