Abstract
Describes a green chemical
process employing nano-particle gold as the catalyst and ionic liquids (IL) as
solvent for the methane oxidation.
Researchers studied the
influence of the amounts of Au/SiO2 and the ionic liquid on the
conversion of methane at reaction temperature of 90 °C. The main product is
methanol, which exists as the methyl group of the methyl trifluoroacetate. The
conversion of methane in the recycled system remains as high as 21.75%. The
mechanism of methane to methano conversion, as well as the catalytic action of
the nano-gold, was also discussed.
