主 题：UiO-66 framework Metal-thiocatecholato Photocatalytic hydrogen evolution Inherent photosensitizer
摘 要：Photocatalytic hydrogen evolution reaction(HER)represents one of the most promising technologies for sus-tainable *** though metal-organic framework(MOF),comprising rich topologies and tunable functionalities,is getting attention as a new generation of photocatalyst,a majority of them only provide unclear active sites along with the use of external noble-metal based photosensitizers and environmentally unfriendly ***,it is urged to develop MOFs possessing structurally unambiguous active sites along with inherent photosensitizing units and execute photocatalytic HER with greener sacrificial ***,we report a UiO-66-type framework,namely UiO-66-dcbdt-Cd(dcbdt^(2-)=1,4-dicarboxylatebenzene-2,3-dithiol),bearing Cd-thiocatecholato moieties as intrinsic photosensitizing units and structurally well-defined active sites for photocatalytic HER in H_(2)***-66-dcbdt-Cd gave the best HER yield of 5.29 mmol g^(-1)and rate of 1.32 mmol g^(-1)h^(-1),outperforming the negligible HER performance of pristine metal-free *** work provides insight to manipulation of thhiocatecholate functionalities inside MOFs to construct inherent photosensitizing units as well as stable structurally unambiguous active sites for sustainable photocatalytic applications.
