    Contact process - Wikipedia

    The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum used to be the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V 2 O 5) is now preferred.

    Contact - Sulphuric Acid

    The 'lead chamber' process was up to that point the main method of sulphuric acid production. Research was undertaken to develop a process whereby sulphur dioxide (SO2) and oxygen (O2) are reacted together in the presence of a catalyst to form sulphur trioxide (SO3). The so-called 'contact process' came into initial use with platinum as.
