| Abstract: | The present study is focused on the influence of Pt loading on the reactivity of catalysts prepared supporting the metal on novel core–shell molybdenum substrates. The electrocatalytic activity and stability of nine Pt/X@MoO3/C catalysts (where X denotes the nature of Mo-phases in the core of the core–shell Mo-particle: Mo2C, MoO2 and/or Mo0) with three Pt loading (5, 20 and 30 wt% Pt) were tested for carbon monoxide and methanol electro–oxidation reactions. |
