Electrocatalysis could play an important role in the transition to sustainable energy sources as it enables the conversion of electrical energy to chemical energy and vice versa. Such conversions are central to the scaled use of renewable sources as well as to the development of strategies for the efficient use of fossil resources. Molecular electrocatalysts are advantageous as their tunable nature allows for a detailed level of understanding and control of reactivity. Yet, homogeneous electrocatalysts often suffer from limitations including: 1) catalyst crossover between anode and cathode (preventing separation of the two half-cell reactions), 2) catalytic activity limited by diffusion to the electrode, and 3) a lack of stability of the catalyst. Immobilization of molecular catalysts on supports for electrocatalysis is a cutting-edge strategy that can potentially address these drawbacks while facilitating selective substrate oxidation using well-defined catalytic active sites. In this context, we have prepared Ir molecular catalysts attached to ordered mesoporous carbon (OMC) using covalent and non-covalent methodologies and tested the new materials for eletrocatalytic water oxidation. Highlights of these strategies along with catalytic results will be discussed.<br/>
