Abstract

The effect of the preparation method on the activity and stability of Ni-Cu-CeO₂ oxide catalysts have been investigated in the high temperature water-gas shift (HT-WGS) reaction. The highest CO conversion (85%) and selectivity was achieved by the catalyst prepared by evaporation induced self-assembly method (Ni-Cu-CeO₂-SG) at a very high GHSV of 84,000 h^-1. The improved performance of the catalyst was attributed to the mesoporous nature of the Ni-Cu-CeO₂-SG which can provide higher surface area and facilitate the easier diffusion of gas through its mesoporous channels.
