Abstract

We report a “two-bird-with-one-stone” strategy for photocatalytic air purification through the positive effect of ozone by surface modification over commercial TiO₂. The understanding of the photocatalytic degradation mechanism of volatile organic compounds is refreshed on the basis of in situ spectroscopic and theoretical studies.
