Low-temperature PROX (preferential oxidation) on novel CeO(2)-supported Cu-cluster catalysts under fuel-cell operating conditions.

ABSTRACT

Cu(1+)-clusters on a CeO(2) support, which were prepared by hydrothermal synthesis using cetyltrimethylammonium bromide (CTAB), were found to be highly active and selective for preferential oxidation (PROX) of CO in excess H(2) with H(2)O and CO(2) under practical fuel-cell operating conditions.
