A self-reductive mesoporous CuOJFe/silicate nanocomposite as a highly active and stable catalyst for methanol reforming

摘要

A simple and convenient one-pot synthetic route to directly prepare a self-reductive mesoporous copper-iron-silicate (CuO_x-Fe-silicate)-based catalyst has been developed. The resultant catalyst is highly active and stable in methanol reforming without needing a pre-reduction procedure. The on-board hydrogen production by reforming methanol is one of the key issues for the development of polymer electrolyte fuel cells (PEMFC). Cu-based catalysts, such as Cu/ZnO and Cu/ZnO/Al_2O_3, are commonly used for methanol steam reforming due to their high catalytic activity.
