Highly Efficient Photocatalytic Degradation of Hydrogen Sulfide in the Gas Phase Using Anatase/TiO₂(B) Nanotubes.

ABSTRACT: Hydrogen sulfide (H₂S) is a highly toxic and corrosive gas that causes a foul odor even at very low concentrations [several parts per billion (ppb)]. However, industrially discharged H₂S has a concentration range of several tens of ppb to several parts per million (ppm), which conventional methods are unable to process. Therefore, advanced and sustainable methods for treating very low concentrations of H₂S are urgently needed. TiO₂-based photocatalysts are eco-friendly and have the ability to treat environmental pollutants, such as low-concentration gases, using light energy. However, there are no reports on H₂S decomposition or oxidation at concentrations below several ppb. Therefore, in this study, we employed anatase/TiO₂
