Supercritical antisolvent precipitation of TiO2 with tailored anatase/rutile composition for applications in redox catalysis and photocatalysis

- TiO2 made by supercritical antisolvent precipitation of various titanium alkoxides.
- In situ XRD used to obtain conditions required to tailor a anatase/rutile mixture.
- Sub 1 nm Au/Pd nanoparticles on anatase rich TiO2 active for H2O2 synthesis.
- ∼1 nm Au/Pd on TiO2 with 10% rutile active for selective alcohol oxidation.
- Pt/TiO2 made by supercritical antisolvent precipitation active for photocatalysis.
