Abstract The increasing demands for clean energy have triggered tremendous research interests on electrochemical energy conversion and storage systems with minimum environmental impact. Electrolytic water splitting holds the promise for global scale storage of renewable energy, e.g., solar and wind in the form of hydrogen fuel, enabling the continuous usage of these diffusive and intermittent energy sources when used together with fuel cells.1,2 Nevertheless, the widespread application of water splitting technology has been severely constrained by the use of precious metal catalysts, such as oxides of ruthenium and iridium for the anodic oxygen evolution reaction (OER), and platinum for the cathodic hydrogen evolution reaction (HER). This presentation concerns our recent progress in developing non-precious metal-based, carbon-based and metal-organic framework (MOF)-based water splitting catalysts, as well as our strategies for enhancing the efficiency of these catalysts by nanostructuring to a level comparable to that of precious metal catalysts.3-11 The commercialisation of some our catalysts in water electrolysis industry also will be discussed.
