摘要

Metal organic frameworks (MOFs) have attracted great interest inphotocatalysis, but their activity is hampered by the issue of severe carrierrecombination. Here, through a carboxyl group assisted coordination route,MXene decorated with carboxyl groups provides chelation sites enablingcoordination with UiO-66-NH_2(Zr/Ti) (UZT) to fabricate a tightly connectedUiO-66-NH2(Zr/Ti)/carboxyl-functionalized MXene (UZT/CFMX) heterostructure.This is the first instance of direct chemical bonding of MOFs-involvedheterostructure via a coordination bond. The critical role of decoratedcarboxyl groups can be determined so that 1) these can help to establish astrong coordination bond between two materials; 2) act as bridge to promotethe electrons transfer from MOFs to MXene, thus relieving carrier recombination,and 3) most interestingly, the carbon atom on the carboxyl groupforms a bond with the oxygen from water stimulating the water to dissociateinto OH* and H*, thus adding additional reaction pathways for promotingphotocatalytic water splitting. Accordingly, the resulting UZT/CFMX showsefficient solar-driven photocatalytic performance for water splitting. The H2evolution rate is as high as 2187 μmol g~（?1） h~（?1）, 20 times higher than that ofUZT and 4 times higher than that of UiO-66-NH_2 (Zr/Ti)/MXene (UZT/MX),also surpassing the majority of reported MOF-based photocatalysts.
