Influence of the phase composition of titania on catalytic behavior of Co/TiO2 for the dry reforming of methane

The phase transfer of TiO2 from anatase to rutile for a 10 wt% Co/TiO2 catalyst during the reduction causes serious disappearance of activity at 0.1 MPa during CH4/CO2 reforming, whereas the transfer for 0.5 wt% Co/TiO2 brings about relatively stable activity at 2 MPa.
