Catalytic ethanol steam reforming for hydrogen production was investigated over Co/K/a-Al2O3 with various K loadings. The K loading on Co/a-Al2O3 was effective for not only increasing H2 yield and ethanol conversion but also suppressing coke formations. XAFS, XPS, and H2-TPR measurements revealed that reduction of the supported Co was suppressed by K loading. It was considered that the partially reduced Co species (CoO) might be active species for ethanol steam reforming.
