A Ti-based bi-MOF for the tandem reaction of HO generation and catalytic oxidative desulfurization
In the past, H 2 O 2 has been used as an oxidant when Ti-based materials are used as catalysts at ambient conditions. However, H 2 O 2 suffers from high cost and safety concerns. Therefore, replacing H 2 O 2 with O 2 has been highly desired. In this study, a Ti-based bi-MOF, MIL-125(Ti)@NH 2 -MIL-12...

has been used as an oxidant when Ti-based materials are used as catalysts at ambient conditions. However, H
2
O
2
suffers from high cost and safety concerns. Therefore, replacing H

2
with O

has been highly desired. In this study, a Ti-based bi-MOF, MIL-125(Ti)@NH
2
-MIL-125(Ti) has been synthesized through the internal extended growth of MIL-125(Ti) on NH
2
-MIL-125(Ti). This Ti-based bi-MOF performed in sequence to synergistically catalyze the oxidative desulfurization (ODS) reaction with O
2
. In this bi-MOF catalyst, MIL-125(Ti) is partly embedded and well distributed on the surface of NH
2
-MIL-125(Ti). NH
2
-MIL-125(Ti) serves as a catalyst for the production of H
2
O
2
from O
2
/methanol under visible light, while MIL-125(Ti) serves as an ODS catalyst. The ODS over MIL-125(Ti) is the most effective as the
in situ
generated H
2
O
2
could be used fully, and the consumed H
2
O
2
(ODS reaction) also promotes further H
2
O
2
production through the Le Chatelier's principle. MIL-125(Ti) and NH
2
-MIL-125(Ti) exist in close proximity in the bi-MOF material, which leads to an increase in the catalytic efficiency by 2.5-fold in comparison to that obtained from their physical mixture.
