Solution

In the manufacture of Nitric acid, the first step is catalytic Oxidation of Ammonia.
And the catalyst used for the manufacture of ammonia is platinum( $P t$ ).
The equation for the manufacturer is,
$\underset{A m m o n i a}{4 N H_{3} (g)} + 5 O_{2} (g) \to_{880 ° C}^{P t} 4 N O (g) + 6 H_{2} O (l) \underset{N i t r o g e n o x i d e}{2 N O (g)} + O_{2} (g) \to 2 N O_{2} \underset{N i t r o g e n d i o x i d e}{4 N O_{2} (g)} + 2 H_{2} O (l) + \underset{O x y g e n}{O_{2} (g)} \to \underset{N i t r i c a c i d}{4 H N O_{3} (l)}$
So, the name of the catalyst is platinum.
