Black TiO

and metal-organic frameworks (MOF) are great materials with light-harvesting ability, redox power and consequently catalytic activity. Here, the integration of MIL-100(Fe) with TiO
2
(B) composite was designed for photocatalytic application, which greatly promoted light-harvesting and charge transfer. As expected, the integrated TiO
2
(B)/MIL-100(Fe) composite showed high photocatalytic activity due to unique Fe-O-Ti bonds that were constructed, which acted as an electronic tunnel to reduce electronic transfer resistance between MIL-100(Fe) and TiO
2
(B). In addition, the presence of Fe-O clusters in MIL-100(Fe) can also promote the charge dissociation and improve catalytic activity

redox cycle. This achievement would help us to understand and design charge transfer pathways in the integration of MOF/semiconductor photocatalysts.
