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

A hydrophobic MOF, OPA/MIL-125-NH2, whose Ti cluster was alkylated with octadecylphosphonic acid (OPA), was found to enhance photocatalytic H2O2 production in a two-phase system. Its activity exceeded that of linker-alkylated MIL-125-NH2. OPA/MIL-125-NH2 was modified on its outermost surface, which resulted in the activity enhancement while preserving the inner pores of the inherent MOF.
