Fig. 1. (a) Surface modification of mesoporous TiO2 generates functional materials. (b) Select Ti-MOF SBU structures (MIL-125, PCN-22, MOF-901, and DGIST-1). (c) Schematic illustration of novel Ti3(OH)2 SBUs in Ti3–BPDC and their metalation to generate anchored CoII-H species for cascade reduction of N-heteroarenes.
