  ABSTRACT: 39 mol% SiC of ceramic pellets ZrB2-αSiC and TiB2-αSiC were synthesized by the reactive hot pressure RHP process at 1850°C under 40 Mpa in vacuum. The XR diffraction displays the absence of other reagents apart from ZrB2, SiC and TiB2 confirming the purity of the pellets. The cathodic exploitation of both of them through electrochemical study shows that TiB2-αSiC is the most active for Hydrogen Evolution Reaction (HER) and Hydrogen Oxidation Reaction (HOR) in 0.5 M of H2SO4 solution at room temperature. Moreover, the kinetic exploitation shows that for both pellets the system is controlled by mass transport when they are used as HER. However, in the case of HOR, the system is controlled by the electron transfer.
