Interfacial engineering of MOF-on-MOF heterostructure for efficient charge separation and photoelectrochemical water splitting
Interfacial engineering of MOF-on-MOF heterostructure for efficient charge separation and photoelectrochemical water splitting
研究概述
在α-Fe2O3上依次构筑MIL-125(NH2)/UiO-66双MOF异质结构,借助Fe—Ti/Fe—O—Ti连接、能带匹配及内建电场改善空穴分离与水氧化。优化光阳极在1.23 V(相对RHE)达到1.93 mA/cm²,并延长空穴寿命、提升电荷转移效率及稳定性。
