“…Finally, these crystals were dried in vacuum at room temperature overnight to generate solvent-free samples, which were preserved avoiding exposure to air and moisture. 22 with a slight modification, by dissolving 0.4 g of ground WO 3 •H 2 O into 10 mL of H 2 O 2 (30%) and stirring at 60 °C for 5 h. This solution was cooled down naturally to room temperature and used as the precursor for the growth of tungsten oxide and its hydrate nanoparticles inside the MOF pores. To control the amount of nanoparticles inside MOF, different volumes of this precursor solution were used (Table S1).…”

We report the construction of molecular compartments by the growth of narrow-band semiconductor nanoparticles, tungsten oxide and its hydrate, in the mesopores of a metal–organic framework (MOF), MIL-100-Fe. The location of these nanoparticles in pores and their spatial arrangement across the MOF crystal are unveiled by powder X-ray diffraction and small-angle neutron scattering, respectively. Such a composition with pore-level precision leads to efficient overall conversion of gas-phase CO2 and H2O to CO, CH4, and H2O2 under visible light. When WO3·H2O nanoparticles are positioned in 2.5 nm mesopores with 24 wt %, the resulting composite, namely, 24%-WO3·H2O-in-MIL-100-Fe, exhibits a CO2 reduction rate of 0.49 mmol·g–1·h–1 beyond 420 nm and an apparent quantum efficiency of 1.5% at 420 nm. These performances stand as new benchmarks for visible-light-driven CO2 overall conversion. In addition to the size and location of semiconductor nanoparticles, the coordinated water species in the crystal are found critical for high catalytic activity, an aspect usually overlooked.
