Direct methane conversion to methanol by ionic liquid-dissolved platinum catalysts [PDF]
, 2006 Ternary systems of inorganic Pt salts and oxides, ionic liquids and concentrated sulfuric acid are effective at catalyzing the direct, selective oxidation of methane to methanol and appear to be more water tolerant than the Catalytica ...
