We investigated ethanol steam reforming over Co particle catalysts at 723K. The Co particle catalysts showed higher activity and produced more H_2 than any of the supported Co catalysts examined. As the ethanol partial pressure was increased from 317 to 3756 Pa, production of CH_4 over Co particle catalysts was suppressed relative to that observed previously over Rh catalysts. Highly selective production of H_2 and CO_2 was achieved over Co particle catalysts prepared from Co(C_5H_7O_2)_2・2H_2O. X-ray diffraction and thermogravimetric analysis of the Co particle catalysts suggested that during the steam reforming reaction, the catalysts were mostly reduced to metallic Co, which was the active catalytic species.
