Summary: The development of bifunctional water-splitting electrocatalysts that are efficient and stable over a wide range of pH is crucial but challenging. This study reports an atomically dispersed Ru/Co dual-sites catalyst anchored on N-doped carbon (Ru/Co-N-C) for excellent oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in both acidic and alkaline electrolytes. The catalyst shows superior performance compared to benchmark catalysts Pt/C and RuO2, with low overpotentials and high current densities. Theoretical calculations and experimental results demonstrate that the introduction of Co-N4 sites into Ru/Co-N-C modifies the electronic structure of Ru and enhances the bonding strength with oxygen/hydrogen intermediate species, leading to improved OER and HER performance. Furthermore, the incorporation of Co-N4 sites improves the corrosion-resistance of Ru/Co-N-C during electrolysis. The Ru/Co-N-C catalyst has been successfully applied in a proton exchange membrane water electrolyzer and shows stable operation at a high current density.

Summary: The rapid development of aerospace weapons and equipment, wireless base stations, and 5G communication technologies has increased the demands for polymer-based electromagnetic interference (EMI) shielding composites. However, most of these composites fail to combine high performance and multi-functionality. In response, three possible directions for overcoming these limitations have been proposed, including the construction of efficient conductive networks and the optimization of multi-interfaces for lightweight and multifunction compatibility. This research aims to provide a theoretical basis and technical guidance for the preparation and development of polymer-based EMI shielding composites.
