New hybrid materials of exfoliated layered double hydroxide nanosheet (LDH
NSs) and metal-organic frameworks (MOFs) were successfully syntheized. A
colloidal suspension of LDH NSs was firstly prepared through hydrothermal
reaction for powdery LDH (i.e., ZnCr-LDH) and its exfoliation process in organic
solvents (e.g. formamide, dimethylformamide). The MOF/LDH hybrid materials
were developed by the crystal growth of MOF(i.e., MIL(Ti)-125-NH 2 ) in the
colloidal suspension of LDH Ns. The obtained hybrid materials were
systematically characterized by various tools such as powder XRD, SEM, TEM,
BET, FT-IR, UV-Vis and so on. The hybrid materials were carried out tests of
photocatalytic water splitting under visible light irradiation (λ≥420 nm) and we
found that its performances were better than those shown by individuals. In
particular, the hybridization with layered inorganic nanosheets enhanced the
structural stability of MOF, which is attributed to the strong coupling of MOF
with functional groups on the surface of robust inorganic nanosheet. In this
presentaion, synthesis procedure and mechanism, structural formation, several
applicaions for the hyrbid meterials will be discussed in detail. Obviously, the
current study demonstrates the advantages of the hybridization with inorganic
nanosheet not only in improving the structural stability of MOF but also in
optimizing the functionality of this material.
