Oxidation of Sulphur Dioxide using Micro‐ and Nanoparticles of various Iron Oxides

Abstract: Sulphuric acid is the chemical with highest production rates in the world. At present, it is mainly synthesized using vanadium pentoxide as catalyst, which determines the applied production process particularly in terms of gas pre‐treatment and heat management. For processes, which cannot be run with vanadium pentoxide, alternative catalysts are required to make different SO2 qualities accessible to sulphuric acid production. Ferric oxides are a very promising alternative, since they combine higher thermal wit… Show more

“…1,2 Prominent examples are the Haber-Bosch process for ammonia synthesis, 3 the cracking of long-chain hydrocarbons in the petroleum industry, 4 and the oxidation of sulphur dioxide to sulphur trioxide finally yielding sulphuric acid. 5,6 The improvement of such catalytic systems crucially depends on a detailed understanding of the reaction mechanisms at the atomic scale that are governed by the potential energy surface (PES), which is a high-dimensional function providing the energy and forces for any given atomic configuration. Thus, the PES determines the dynamics of the reactants at the surface, the making and breaking of bonds and, finally, product formation.…”
