主 题：Electrocatalysis Interfacial interactions Layered double hydroxide Metal–organic frameworks (MOFs) Water splitting
摘 要：Designing hybrid materials with numerous catalytic active sites,high specific surface area,and interfacial interactions is an effective strategy to improve electrocatalytic *** this work,iron-based metal organic frameworks（Fe-MOFs）@（Co,Ni）Fe-layered double hydroxide（LDH） is successfully constructed using the similar MOF growing on LDH strategy for oxygen evolution reaction and hydrogen evolution reaction in the alkaline *** synthesized hybrid materials in this particular way show excellent electrochemical overall water-splitting performance with the cell voltage of 1.62 V at10 mA·cm-2in the alkaline environment due to the optimized adsorption/desorption properties of metal ions on oxygencontaining species and interfacial effects of hybrid ***-MOFs@（Co,Ni）Fe-LDH also exhibits excellent hydrogen and oxygen production efficiency of 370 and 175 μL·min-1,*** work draws on an effective approach to the fabrication of MOF@LDH structures and provides new insights into overall water-splitting in alkaline conditions.
