Which catalyst used the following reaction?

$2C{H}_4\left(g\right)+O_2\left(g\right)\to 2C{H}_3\mathit{OH}\left(g\right)$

The catalyst used in the given reaction is $\mathit{NaHC}{O}_3$.
Oxidation reaction is defined as the reaction that takes place when a substance comes in contact with oxygen or other oxidising substances. Oxidant is nothing but molecular oxygen. The catalyst used in the given reaction is alkaline $\mathit{aHC}{O}_3$ . Methane is converted to methanol in presence of  $\mathit{NaHC}{O}_3$. Methane undergoes oxidation to form methanol.
