Oxidation of ammonia into nitric oxide in the presence of platinum gauze in Ostwald’s process

In Haber's process ammonia is produced from nitrogen and hydrogen 

${\mathrm{N}}_2\left(\mathrm{g}\right)+3 {\mathrm{H}}_2\left(\mathrm{g}\right)\stackrel{\mathrm{Fe}\left(\mathrm{s}\right)}{\to }2 {\mathrm{NH}}_3\left(\mathrm{g}\right)$

Oxidation of ammonia into nitric oxide in the presence of platinum gauze in Ostwald’s process

$4{\mathrm{NH}}_3\left(\mathrm{g}\right)+5{\mathrm{O}}_2\left(\mathrm{g}\right)\stackrel{\mathrm{Pt} \left(\mathrm{s}\right)}{\to }4\mathrm{NO}\left(\mathrm{g}\right)+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$

During the Contact Process for manufacturing sulfuric acid, sulfur dioxide has to be converted into sulfur trioxide, which is done by passing sulfur dioxide and oxygen over a solid vanadium(V) oxide catalyst
