Unveiling Trifunctional Active Sites of Heteronanosheet Electrocatalyst for Highly Efficient Integrated Cascade Battery/Electrolyzer Systems |
| 초록 |
We identify the unique trifunctional active sites of ReS2 and NiFe layered double hydroxide (NiFe-LDH) heteronanosheets (ReS2/NiFe-LDH) for integrated cascade Zn-air battery/electrolyzer systems. Along with the edge and surface sites of NiFe-LDH for both oxygen evolution reaction and oxygen reduction reaction activities, the unprecedented activity of the ReS2/NiFe-LDH heteronanosheets for hydrogen evolution reaction is emerged from the S-O bonds at the heterointerfaces, in coupled with the strong coupling effect and vertical alignment of NiFe-LDH and ReS2. The outstanding trifunctional activities and the mechanism understanding ensure the use of ReS2/NiFe-LDH heteronanosheets for the development of integrated cascade battery/electrolyzer systems, showing great promising for the cost-effective energy storage and H2 production applications ranging from the distributed households to the assembly for electrical vehicles. |
