Summary: The study revealed that the photocatalytic activity of rutile Pt/TiO2-x significantly increased with the reduction temperature, while the activity of anatase Pt/TiO2-x decreased and that of brookite Pt/TiO2-x remained unchanged. Electron-spin resonance analysis showed that rutile and brookite had similar defect sites after reduction, while anatase exhibited different resonance signals. The research demonstrated that the depth of inherent midgap states, depending on crystal phases, influences defect generation and subsequently impacts the photocatalytic performance of Pt/TiO2-x.
