摘      要：Decoration of metal-organic framework(MOF)has been considered as an effective route to improve the photoelectrochemical(PEC)performance of TiO_(2),but there is still a lack of understanding of the regulatory ***,Ni-MOF was rationally introduced by in-situ etching method,which helps for artificially regulating the coordination state of Ni *** photocurrent density(0.81 mA/cm^(2))and IPCE value(33.1%)of TiO_(2)-MOF-2 are about twice higher than that of pristine TiO_(2) due to the rich unsaturated sites of ***,the saturated coordination has caused the decline of PEC performance because of the obvious steric ***,this work presents an insight for the effect of coordination state on PEC activity especially in MOF system.
