Abstract:
Metal-support interaction represents an effective strategy to boost the electrocatalytic performance of electrocatalysts. Herein, a novel electrocatalyst consisting of Ru nanoclusters anchored on the N-doped carbon nanosheets (abbreviated as Ru@N-CNS hereafter) with synergistic strong metal-support interaction (SMSI) and reactive metal-support interaction (RMSI) is developed. Thanks to the equilibrium of SMSI and RMSI, the obtained Ru@N-CNS electrocatalyst possesses abundant exposed active sites, robust mechanical strength, fast mass transfer, and regulated electronic states, thereby holding outstanding electrochemical hydrogen evolution performance in alkaline medium. To be specific, the Ru@N-CNS only requires a small overpotential of 16 mV at a current density of 10 mA cm-2, low Tafel slope of 67.8 mV dec-1, and highlighted long-term stability, surpassing the commercial Pt/C and Ru/C. More memorably, a water-splitting electrolyzer built by the Ru@N-CNS electrode as cathode and commercial RuO2 as anode needs a low cell voltage of 1.56 V at 10 mA cm-2 and exhibits excellent stability, reflecting a huge prospect for scalable electrochemical H2 generation. This work opens up a novel thought of synergizing metal-support interactions for designing progressive electrocatalysts in energy-related fields.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
