Selective oxidation of methane by using aqueous hydrogen peroxide solution as oxidant was investigated. Colloidal nanosized Cu‐Fe‐silicalite‐1 was prepared and a micro reactor was used to intensify mass transport. It was found that the oxygenate productivity could be enhanced nearly three orders of magnitude while simultaneously ensuring high turn‐over‐frequencies of some 100 h −1 . However, the main product in liquid phase was not methanol, but formic acid. At optimized reaction conditions, a selectivity to formic acid of 96.7 % at a methane conversion of 10.3 % could be achieved.
