Boosting visible light photocatalytic oxidation of CO using Au nanocatalysts through synergistic preparation of an Fe-doped TiO2 support and cold plasma treatment

Treating Au species on Fe-doped TiO 2 (Fe@TiO 2 ) with cold plasma favors the formation of highly active Au–Fe@TiO 2 interfaces, which renders the fabricated Au catalyst with outstanding visible light photocatalytic activity for CO oxidation.
