In situ conversion builds MIL-101@NiFe-LDH heterojunction structures to enhance the oxygen evolution reaction
文献摘要：
The construction of rich phase interfaces to increase active reaction area in hybrid materials is an excel-lent strategy to improve electrochemical performance.Under this guideline,MIL-101@OX-metal organic framework(MOF)is constructed by the"MOF on MOF"method,then converts to MIL-101@NiFe-layered double hydroxides(LDH)by in situ transformation in alkaline solution.MIL-101@NiFe-LDH shows ex-cellent electrochemical water oxidation performance.It needs only an overpotential of 215 mV to drive 10 mA/cm2 of oxygen evolution reaction(OER),which is less than that of NiFe-LDH,MIL-101.In addition,MIL-101@NiFe-LDH has the smallest Tafel slope(55.1 mV/dec)compared with NiFe-LDH(61.1 mV/dec),MIL-101(150.8 mV/dec).The excellent water oxidation activity is due to the high phase interfaces de-rived from high specific surface area of MOF.This work offers an alternative method for making MOF/LDH heterostructures with an optimized phase interfaces and provides new insights for OER.
