Ti cluster-alkylated hydrophobic MOFs for photocatalytic production of hydrogen peroxide in two-phase systems

A hydrophobic MOF, OPA/MIL-125-NH 2 , whose Ti cluster was alkylated with octadecylphosphonic acid (OPA), was found to enhance photocatalytic H 2 O 2 production in a two-phase system. Its activity exceeded that of linker-alkylated MIL-125-NH 2 . OPA/MIL-125-NH 2 was modified on its outermost surface...

Description
Summary:A hydrophobic MOF, OPA/MIL-125-NH 2 , whose Ti cluster was alkylated with octadecylphosphonic acid (OPA), was found to enhance photocatalytic H 2 O 2 production in a two-phase system. Its activity exceeded that of linker-alkylated MIL-125-NH 2 . OPA/MIL-125-NH 2 was modified on its outermost surface, which resulted in the activity enhancement while preserving the inner pores of the inherent MOF. The photocatalytic activity of a cluster-alkylated MOF for H 2 O 2 production far exceeded that of a linker-alkylated MOF in a benzyl alcohol/water two-phase system.
