Producing oxide catalysts by exploiting the chemistry of gliding arc atmospheric plasma in humid air

摘要: Abstract Nanostructured metal oxides are good candidates for applications in heterogeneous catalysis. Recently our consortium has developed the preparation of such materials by exploiting redox properties non-thermal gliding arc plasma (glidarc) humid air. This contribution aims at sharing with community active field catalysis that glidarc technique is an easy and accessible, but powerful a very bright future can be used producing oxide catalysts. Therefore, we present here most recent achievements titanium, iron manganese catalysts using glidarc. TiO2 nanorods containing both rutile anatase phases improved photocatalytic activity under visible light were obtained oxidizing Ti3+ ions aqueous solution species. Fe2+ exposed to discharge transformed into sea-urchin-like porous goethite (α-FeOOH) nanostructures via consecutive oxidation-hydrolysis processes. The synthesized was mesoporous high surface area. Clay supported also prepared depositing particles on kaolinite. Those (and their calcination products) Fenton degradation organic dyes. α-MnO2 rapid reduction MnO4− after exposing potassium permanganate discharge.
