Abstract:The electrochemical partial oxidation of methane (CH 4 ) to value-added chemicals under ambient conditions provides a solution for harnessing abundant natural gas resources. Here, we investigate α-Fe 2 O 3 as a model catalyst to gain a mechanistic understanding of the electrochemical CH 4 oxidation reaction (eCH 4 OR). During chronoamperometric experiments, we obtain liquid products (formic acid, acetic acid, and acetone) with ∼6.5% total Faradaic efficiency at 2.3 V versus the reversible hydrogen electrode (V… Show more
