WebHeterogeneous catalysts are extremely useful because they enable the production of several commercially important products on a relatively large scale. For example, oxides of iron placed on alumina (a chemical compound with the formula Al 2 O 3) are widely used as heterogeneous catalysts in the Haber process for the industrial production of ... WebThe manufacture of nitric acid from ammonia. This is yet another example of heterogeneous catalysis. This process involves oxidation of the ammonia from the Haber Process by oxygen in the air in the presence of a platinum-rhodium catalyst. Large sheets of metal gauze are used in order to reduce expense and to maximise the surface area of the ...
