V2O5 catalyses the oxidation of SO2 in the manufacture of
sulphuric acid TiCl4 with A1(CH3)3 forms the basis of the Ziegler catalysts
used to manufacture polyethylene (polythene) Iron catalysts are used in
the Haber process for the production of ammonia from N2/H2 mixtures Nickel catalysts enable the hydrogenation of fats to proceed
