High surface area (> 100 m{sup 2}/g) SiC doped with zirconium was prepared by the gas-solid reaction. The material was made up of three phases: {beta}-SiC, covered by ZrO{sub 2} and an amorphous phase composed of Si, Zr and O. The characterization of the sample was performed by means of powder X-ray diffraction (XRD), surface area and porosity measurements by the BET method, scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM). Preliminary catalytic tests, the standard n-C{sub 7} isomerization on supported MoO{sub x}C{sub y} showed that this new support was at least as effective as pure SiC.
