主 题：metal-organic framework phosphonates photocatalysis water splitting
摘 要：A novel microporous two-dimensional(2D)Ni-based phosphonate metal-organic framework(MOF;denoted as IEF-13)has been successfully synthesized by a simple and green hydrothermal method and fully characterized using a combination of experimental and computational *** resolution by single-crystal X-ray diffraction reveals that IEF-13 crystallizes in the triclinic space group Pi having bi-octahedra nickel nodes and a photo/electroactive tritopic phosphonate ***,this material exhibits coordinatively unsaturated nickel(II)sites,free-P0_(3)H_(2)and-P0_(3)H acidic groups,a C0_(2)accessible microporosity,and an exceptional thermal and chemical ***,its in-deep optoelectronic characterization evidences a photoresponse suitable for *** this sense,the photocatalytic activity for challenging H_(2)generation and overall water splitting in absence of any co-catalyst using UV-Vis irradiation and simulated sunlight has been evaluated,constituting the first report for a phosphonate-MOF ***-13 is able to produce up to 2,200 fimol of H_(2)per gram using methanol as sacrificial agent,exhibiting stability,maintaining its crystal structure and allowing its *** more,170μmol of H_(2)per gram were produced using IEF-13 as photocatalyst in the absence of any co-catalyst for the overall water splitting,being this reaction limited by the 0_(2)*** present work opens new avenues for further optimization of the photocatalytic activity in this type of multifunctional materials.
