Cover Story: The work carried out in this study was in collaboration with Croda Europe. The key aims were to determine whether Mn-doped titania could remove NO or SO₂ gases. The work used two systems to investigate the reaction with NO and SO₂ with Mn-doped titania surfaces using in situ near-ambient-pressure photoelectron spectroscopy. An atomically clean TiO₂(110) rutile single crystal dosed with Mn was used to examine the reaction between the gases and the titania surface under idealized conditions. This allowed the identification of sulfates and nitrate species at the surface upon exposure to the gases. Croda Mn-doped nanoparticles were then studied, drawing on the information from the single crystal work to confirm that sulfates and nitrates formed again. This suggests that these materials can reduce exposure to oxidizing gases such as SO₂ and NO. View this paper
