• Nickel, copper and cobaltions were intercalated into fluorotetrasilisic mica (TSM) and hectorite (Hect) by an exchanging method. X-Ray photoelectron spectroscopy (XPS) studies indicated that the exchanged cations were intercalated into the interlayer space. After hydrogen treatment at 723K (for Cu catalysts : 523K), the layered structure of TSM was maintained while that of Hect collapsed. In order to investigate catalytic activities using these intercalated catalysts after hydrogen treatment, water-gas shift (WGS) reaction was carried out. The WGS reaction was selectively conducted over Ni/TSM and Co/TSM, while methanation occurred concomitantly over conventional metal-supported catalysts such as Ni/Al_2O_3 or Ni/SiO_2 and Co/Al_2O_3. In the case of supported copper catalysts, hydrogen was the only product observed on the WGS reaction regardless of supports investigated in this work (TSM, Hect, Al_2O_3,Cu/SiO_2).
