Solid carbon spheres chains (CSCs) are new carbon materials with unique physicochemical properties and original organization, they present a distinctive opportunity for creating novel multifunctional composites electrodes for a wide range of electrochemical applications. The electrocatalytic supporting of properties of these CSCs‐coated with a model catalyst that is Pt of different morphologies were studied for the oxidation of ferrocyanide to illustrate their use in electroanalytical applications, for the oxidation of methanol and the reduction of oxygen to exemplify their potential use in energy conversion devices such as fuel cells for instance. The very good catalytic supporting properties demonstrated here are due to the fact that CSCs possess multiple‐points of electrical connectivity and excellent dispersions characteristics for the catalyst that allow the latter to be largely accessible for electrocatalytic reactions.
